Raysession not loading/creating sessions anymore

[rgbeitor]

Hi:

First, thank you for your work and the nice software.

This is related to a different computer/distribution as the ticket:

Buffer cannot be changed anymore from ray session #247

In this case, is a computer that I use every now and then.

OS and kernel version:

openSUSE Tumbleweed 20251007

Linux minelava 6.17.0-2-default #1 SMP PREEMPT_DYNAMIC Thu Oct 2 08:12:40 UTC 2025 (190326b) x86_64 x86_64 x86_64 GNU/Linux

The problem here is that after some update (I guess), raysession is not able to load any of the previous sessions that I have there. It is also not possible to create a new session.

Running it into debug mode, this is the output:

Everything seems fine to me but:

terminate called after throwing an instance of 'std::bad_alloc'
what(): std::bad_alloc

How can I troubleshoot it? It was working since years with the same Tumbleweed distribution, without problems.

Sidenote: I was trying to compile the software. Everything was fine, but:

It is not even starting. I was trying to install the cgi package (pipx install legacy-cgi) but no luck!

Thanks in advance for your inputs

Ah! One more note: I was trying to disable firewall and apparmor, just in case.
Same results

I was also checking the process in memory. It uses 100% of one cpu during a while and then coredump (and message):

terminate called after throwing an instance of 'std::bad_alloc'
what(): std::bad_alloc

Hi ! For the install from source (last version v0.14.4), you have to remove the line 22 in "/home/rgb/bin/RaySession-0.14.4/src/gui/patchbay/patchcanvas/portgroup_widget.py", sorry for this annoyance (bug fixed in git master, I have to make a new release in coming days).

For the error you meet, I really don't know. I tried the source code in a virtual machine (OpenSuse Tumbleweed), but I can't reproduce. It may come from your kernel, but not sure at all.

[rgbeitor]

Hi!
Thank you for your response.

I'll try to modify the file and test again the source code installation.

About the Tumbleweed that I'm using, this is the version:

Linux minelava 6.17.2-1-default #1 SMP PREEMPT_DYNAMIC Sun Oct 12 17:26:11 UTC 2025 (d07fa64) x86_64 x86_64 x86_64 GNU/Linux

Can you please check if it is the same that you use in your virtual machine?

[rgbeitor]

I was checking with the modified source code. I was checking with and without recompiling (I understand that it is not needed, as this is part of the python).
Program starts now, but no audio/midi devices are recognized (black canvas).
Anyhow, I tried to open a existing session and unluckily the same problem:

As you can see, same message:

terminate called after throwing an instance of 'std::bad_alloc'
what(): std::bad_alloc

Behaviour is the same: proocess get's to 100% for a while and then present the error...

[rgbeitor]

Another note:
After the crash, it is not possible to open another session anymore.

[rgbeitor]

UPDATE: I was also checking in a virtual machine. Same distribution, same version of the kernel (exactly!), same update/snapshot level (Tumbleweed is a rolling release). Of course different devices. WORKING.

What can be happening? Why is it crashing in the host device? Howto troubleshoot it? Is there any way to get a -even- more verbose output from raysession?

Thanks in advance...

[rgbeitor]

Last discovery -for today :)

Whenever I launch raysession (in the host), several messages appear in dmesg:

I hope this info helps to clarify where is the problem...
I don't know why I wasn't checking the standard facilities (outside of the raysession log dump)... my bad...!

Sorry, it is very complex for find the source of your problem. I see that ray-jackpatch is crashed by a segmentation fault. It can means that there is a problem with JACK (or Pipewire) itself, but it could be something else.

What would be interesting would be to test the git master version, there are a lot of changes since v0.14.4, including changes affecting ray-jackpatch, and more precise logging.

Hi!
I was doing some more testing this morning, and I was also installing the software (from the official tumbleweed package) in a tumbleweed virtual machine. Interestingly, and as you said, it works fine. Only "strange" thing is that -when I try to save a session- it says "git didn't stop normally" and "can't snapshot". But seems to be working fine nevertheless.

I was checking kernel / tumbleweed snapshot and both are the same in host/vm.
Python is slightly different: 3.13.9 in the host and 3.13.17 in the vm. I don't know if that can affect.

My guess is that there should be some kind of updated/non standard version library in the host machine that creates this behaviour... For example, there are references in the log to "libspa-support.so", but seems to be the same in either the host and the vm.

In Tumbleweed this is provided by the package "pipewire-spa-plugins0_2". Version is exactly the same in both host/vm.

What are the libraries that are in use by the module "ray-jackpatch"?

I was checking the code and it looks like it just launches an instance of main_loop.

Of course, I can try the git master version. But probably is the source code that I was already trying for the tests. I was downloading from:

Is that the newest version?

My hope is try to isolate what is different between host and vm and try to revert it back in the host. I don't know what is the best procedure for that.

Thanks!

Only "strange" thing is that -when I try to save a session- it says "git didn't stop normally" and "can't snapshot"

mhhh, probable that git is not installed in your virtual machine (git is required for snapshots, I have to fix this error when git is not installed, even if I think snapshots are so important that git should be a dependency, and not optional).

Python is slightly different: 3.13.9 in the host and 3.13.17 in the vm. I don't know if that can affect.
same minor version, I think it should not change anything.

What are the libraries that are in use by the module "ray-jackpatch"?

mmhh, IIRC, in v0.14.4, the jacklib distributed with RaySession. In git master, it depends:

• if ray-jackpatch is Internal (you can see Protocol: Internal in client properties), no particular dependency, ray-jackpatch is a module running in the ray-daemon process, it communicates with the ray-patch_dmn module to see patch and connect/disconnect ports
• else (you can see Protocol: NSM in client properties), ray-jackpatch is an independent process, it needs python3-jack-client.

But probably is the source code that I was already trying for the tests. I was downloading from:

Yes, it is this, you're right.

My hope is try to isolate what is different between host and vm and try to revert it back in the host. I don't know what is the best procedure for that.

With the master branch version, you should try ray-jackpatch as NSM client (for example, edit the raysession.xml file removing property protocol=Internal in patch client). And launch it in a terminal (checkbox in client properties dialog). It happens sometimes that some messages coming from clients are missing in the main terminal.

Hi!
And thank you for your comments.

mhhh, probable that git is not installed in your virtual machine (git is required for snapshots, I have to fix this error when git is not installed, even if I think snapshots are so important that git should be a dependency, and not optional).

Ok, no problem. I can deal with that later. I was guessing something so.

if ray-jackpatch is Internal (you can see Protocol: Internal in client properties), no particular dependency, ray-jackpatch is a module running in the ray-daemon process, it communicates with the ray-patch_dmn module to see patch and connect/disconnect ports

What is it by default? internal or external?

else (you can see Protocol: NSM in client properties), ray-jackpatch is an independent process, it needs python3-jack-client.

python3-jack-client wasn't installed neither in the host computer, nor in the vm (and there raysession is working). I was installing it in the host computer to do some more tests and see if anything changes.

With the master branch version, you should try ray-jackpatch as NSM client (for example, edit the raysession.xml file removing property protocol=Internal in patch client). And launch it in a terminal (checkbox in client properties dialog). It happens sometimes that some messages coming from clients are missing in the main terminal.

I was trying to locate the .xml file without luck. Only found:

Neither contains the property "protocol=internal"

Where is located the file to modify? Maybe I'm missing something here...

One more note: The segfault happens as soon as I run the raysession command, NOT when I load the session.

This message:

terminate called after throwing an instance of 'std::bad_alloc' what(): std::bad_alloc

Appears later.

[Houston4444]

What is it by default? internal or external?

Internal. Less memory consumption, avoid one more OSC server, and finally is safer at session close when some clients are quitting wildly (as Ardour does).

python3-jack-client wasn't installed neither in the host computer, nor in the vm (and there raysession is working). I was installing it in the host computer to do some more tests and see if anything changes.

Can work yes, but with empty patchbay (except alsa ports if you have python3-pyalsa).

I was trying to locate the .xml file without luck.

I talk about the session file directly. Load a session, close it and modify its raysession.xml file in the session folder (if needed).

[rgbeitor]

Hi again.

Behavior is different now (I guess that due to some updates):

TUMBLEWEED PACKAGE:

Previously there was a crash even before trying to open a session. Now, it is NOT crashing immediately. No errors shown in dmesg output, no errors shown in "/var/log/messages". To get the error, you need to attempt to open a session.

After trying to open a session, usual crash appears:

2025-10-22T14:17:11.965766+02:00 localhost systemd-coredump[28246]: Process 27279 (ray-daemon) of user 1000 terminated abnormally with signal 6/ABRT, processing...

...

and

terminate called after throwing an instance of 'std::bad_alloc'
what(): std::bad_alloc

In the raysession console.

SOURCE CODE

Similar error here:

2025-10-22T14:32:59.263634+02:00 localhost systemd-coredump[29961]: Process 29511 (ray-daemon) of user 1000 terminated abnormally with signal 6/ABRT, processing...

and also:

terminate called after throwing an instance of 'std::bad_alloc'
what(): std::bad_alloc

In the raysession console.

I was also trying to edit the raysession.xml in my "piano" session, but I still couldn't find a line with the "protocol=internal" info:

raysession.xml: <client id="finger_dru" launched="false" executable="/usr/bin/kate" arguments="/home/rgb/data/music/hydrogen/finger_drumming_A_Notes.txt" name="finger_drumming_A_Notes.txt" desktop_file="//not_found" protocol="Ray-Hack" config_file="" save_signal="0" stop_signal="15" wait_win="false" no_save_level="0" />

Only the protocol="Ray-Hack" info. I was substituting it with protocol="internal", but results where the same.

BOTH CASES

Whenever the software raysession is launched, the following error appears:

2025-10-22T14:28:21.480218+02:00 localhost /usr/libexec/xdg-desktop-portal[2806]: Realtime error: Could not get pidns for pid 29516: Could not fstatat ns/pid: Not a directory

I don't know if it could be related.

[Houston4444]

Behavior is different now (I guess that due to some updates):

The main very recent change is that now Qt6 is the default framework (instead of Qt5), and some bug fixes (almost due to the switch to Qt6).

I was also trying to edit the raysession.xml in my "piano" session, but I still couldn't find a line with the "protocol=internal" info:

I was talking about the ray-jackpatch client. Only ray-jackpatch and ray-alsapatch can be internal, if ray-jackpatch is not internal, then it is a regular NSM client, no problem.
