[SR-Users] Core/ signal 11 Segmenation fault on kamailio 4.3.5

[Daniel-Constantin Mierla]

Hello,

there should be a kamailio-dbg or kamailio-debug rpm/deb package than
can be installed to get the debugging symbols. Install that and grab
again the backtrace to get some useful details.

Cheers,
Daniel
