We seem to have a regular occurrence where one of the child processes is crashing, and causing a coredump.

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?
