yes, run as usual and when it is no longer working attach to a SIP

The master process does not do much, just supervising the other
processes in order to clean.

Do you mean running kamailio as usual and later running:
gdb> attach KAMAILIO_MASTER_PID

is it eating a lot of cpu? Can you attach to it with gdb and do a

Sometimes, with no reason (not just in the
moments of highest traffic)
kamailio gets totally frozen, this is, it doesn't reply to SIP messages,
neither relays them. Then Kamailio cannot be killed (just with -9).
And the worst: when this occurs kamailio logs *nothing*.
or running directly:
$ gdb --args /usr/sbin/kamailio -P /var/run/kamailio/kamailio.pid -m 64 -u
kamailio -g kamailio
In the second case kamailio doesn't fork and doesn't bind to the listening
address. So I assume you mean the first case.
Right.
Could it affect to the performance of the service? If
not, when to run "bt"?
after the problem occurs?
Yes, after the problem occurs. Only the process you attach to is going
to be blocked in gdb, the others should function normally (but they
don't anyhow, as I understood).
Also note that when Kamailio gest frozen there is no
coredump.
I also tell that after running "kamctl fifo address_reload" it takes several
minutes until it get frozen, but it doesn't occur always.
Is it the fifo/pid file there? No error why is not starting again?
Cheers,
Daniel

Might be some race in permissions module induced
by address_reload MI
command.
I suspected it. However it doesn't explain the fact that later kamailio
cannot
be started again (even after killing all the kamailio processes with -9).
Would it make sense?
