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

[Jonathan Hunter]

Hi guys,
We seem to have a regular occurrence where one of the child processes is crashing, and causing a coredump.
Please see the output of the corefile;

The last transaction appears to be a REGISTER message from a User-Agent: SIPAUA/0.1.001 which runs on an android device.
We are looking to reproduce in lab environment but I just wondered if anyone had seen this on this version?  Or can advise on the core dump output?
Thanks
Jon
