[SR-Users] Kamailio 1.5 stops processing messages

[Santiago Gimeno]

Hi,

I'm working with Kamailio 1.5 (rev 5968) and from time to time kamailio
freezes and stops processing messages. Kamailio is working only in UDP. I
really don't know in which conditions this problem is happening: it happens
both in high and low load.
Here is a backtrace of one of the UDP working processes when kamailio is
frozen (all the other UDP process backtraces look similar) :

Any idea of what might be happening?
