[OpenSIPS-Users] OpenSIPs 2.2.3 SegFault

[Răzvan Crainea]

Hi, Ahmed!

OpenSIPS 2.2 is quite an old version and is no longer supported for a 
while. If you have the possibility, I'd suggest you to migrate to 2.4, 
which is a stable LTS - if the issue occurs there, then we are able to 
investigate it and track down the problem.
If you can't do that, you're best chance is to upgrade to the latest 2.2 
release, which is 2.2.7. If that still crashes, there's not that much 
you can do, as 2.2 is out of support now, and you will need to migrate 
to 2.4 anyway.

Best regards,
Răzvan
