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.

Hello List,
We have strange problem with OpenSIPS that happens already second time.
OpenSIPS just stops responding. It is up and running but there is
nothing in the log file.
I can see that there are SIP packets arrives in my tcpdump log but no
response from OpenSIPS.
We also have monit alerts on CPU usage more then 90%.
I had to restart it to make it work.
OpenSIPS was not crashed, I do not have any core dump.
OpenSIPS is running on VMWare virtual machine 2CPU, 2G RAM, it has
512M of shared memory assigned. There are around 1000 phones, which is
not much for OpenSIPS.
This also happens at night when there are not much traffic.
OpenSIPS version 1.8.4
