[OpenSIPS-Users] several crashes in a row

[Bogdan-Andrei Iancu]

Hi Juha,

The backtrace is corrupted and the only useful info I can see from there 
is that the crash is related to libxml2 library (used for parsing the 
XML bodies).

The logs shows that the crashed process is the timer (if I'm not wrong) 
- last messages show the DB cleanup and  the DB flush. And there there 
are no XML parsing ops done....

That is a bit odd...

Regards,
Bogdan
