What is the sc4s version ? 3.4.5

Describe the bug
Hi Team, I have recently upgraded our SC4S BYOE environment from 2.49.3 to 3.4.5 (along with upgrading the underlying Syslog-NG package to match what SC4S wants), however, since doing so, I have observed a range of the JIT compilation errors on startup in Journalctl. Ultimately, it does not stop the SC4S service from running, however, I suspect it may potentially be impacting the parsing or performance of the impacted parsers.

There's limited information on this online, but it looks like it may be to due with the move to PCRE2.

I will post some attachments below:
