[SR-Users] Kamailio Exits With: Segmentation Fault Error 4 in usrloc.so

[Daniel-Constantin Mierla]

Hello,

looks like an invalid listen socket structure, quite strange... what 
version of kamailio do you have?

Also, in gdb, frame 0, can you send the output of:

p *_c
p *_c->sock

You can replace sensitive data (like IP), if you wish.

Cheers,
Daniel
