[Environment]
Centos 7
rocketmq-client-cpp-release-2.2.0.tar.gz
libevent-release-2.1.11-stable.zip

I referred to the previous issue #211
It is said that this is a bug in libevent, and upgrade to version 2.1. X can solve the problem,
But why does this error still occur when we are currently using libevent-release-2.1.11-stable.zip .
Is there any other possibilities that could cause this error to occur

thankyou~
