<div class="moz-cite-prefix"><tt>Hi Stas,<br>
<br>
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.<br>
<br>
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.<br>
<br>
