[OpenSIPS-Users] OpenSIPS freeze

[Bogdan-Andrei Iancu]

Hi Stas,

It looks like one of the processes gets stuck in doing something (maybe 
an I/O ?) while keeping a lock - the rest of processes will get one by 
one stuck in that taken lock.

This is not easy to debug - as a start you could try to get a bt from 
each opensips script. Opensipsctl for 1.11 can do that for you via the 
"trap" command. Of course, you can do the same with a small shell script 
doing gdb+bt for all opensips processes.

Regards,
