Hi,
I have experienced a new lock. I have seen that 4 of the UDP worker
processes, but not all, have gone 100% cpu. Kamailio was still able to
process messages through the rest of UDP worker processes. By checking
the logs I can see that the 4 blocked processes have stopped handling
messages at the same time.
I have attached to the blocked processes and the backtrace looks
similar to the previous one except that it seems that the lock is not
exactly related to t_replicate.

I hope this provides some new hints on what might be happening.
