How are these libs installed?
Cheers, Daniel

Daniel,
Thanks for the tip, recompiled and got a new trace
Not sure what happened, but sometimes running kamctl trap restores Kamailio functionality to accept connections.
Thanks in advance!

Hello,
is libssl/libcrypto compiled/installed with debugging symbols? They are not shown in the backtrace.

Hello,
I'm continuing investigations on Kamailio and stress test. Got it again in the state where it's not accepting any new TCP/TLS connections (UDP still works though), but all looks good from lsof/netnstat part, like system is not reporting any zombie connections. Restart of Kamailio process helps
This time I got output of kamctl trap
Put it here: https://pastebin.com/iYrNZ8U9

Can you please help to read gdb output and understand where I missed in config?
Thanks in advance!
