[SR-Users] segfault kamailio 4.4.6 Registrar

[Daniel-Constantin Mierla]

Hello,

the backtrace is incomplete or corefile truncated, not much useful
information out of it. Like it was suggested, the best is to move to a
maintained series, 4.4 is pretty old for a devel to remember easily what
issues were at that moment and fixed meanwhile.

Cheers,
Daniel
