Hello,

if you can reproduce it, try to get the core dump, some steps that will help getting one easier:

- run as root
- before starting do: 'ulimit -c unlimited'

Retest in order to get the issue again and if you get the corefile, then send the backtrace:

gdb /path/to/kamailio /path/to/corefile
bt full

Cheers,
Daniel

Hey Guys,

After upgrading from 3.2.x to 3.3.0 (out of debian packages and
fixing db side) Kamailio is crashing on processing REGISTER. This
crash only happens for updates (or if a stale contact for the same AOR
is already present), not initial REGISTERs.

Attached you can find the log taken with debug=6 as well as the
REGISTER package producing the segfault.
