[OpenSIPS-Users] OpenSIPs crashed

[Ahmed Munir]

The version currently running is 1.6.3.  Today again we got the opensips
crashed issues i.e. 5 out of 8 were crashed due to below message (common on
all 5);

Jan 12 10:07:36 QORCLPSIPROXY02 kernel: opensips[2820]: segfault at 0 ip
00000000004a2936 sp 00007fff5cfaa430 error 6 in opensips[400000+13a000]

We would like to know why we are getting this segmentation fault? Is there
a way to backtrace the issue as don't have the core dump? Further added,
did someone faced this similar issue(s) in past and got this fixed without
upgrade?

Note: we are running opensips for quite a while didn't faced this kind of
issue and there is no changes made on opensips routing script.
