Hello,
when Kamailio is not processing sip messages, so it looks like stuck,
you can grab the backtraces with gdb to see what each kamailio process
is executing at that moment. You need gdb installed and then run:
kamctl trap
It writes to a file in /tmp, the file name is printed by the command.
Cheers,
Daniel

I've encountered a very similar problem in the
past.The siptrace
module uses UDP and does not expect a response, so it can be confusing
that kamailio's behavior changes depending on whether the homer server
is online.
The problem I've seen in the past is that when kamailio and a statsd
server are in the same IP subnet, and the statds server goes offline,
an ARP request is made whenever traffic is to be sent, and this ARP
request is blocking until it times out (a few seconds). It blocks all
workers because they all want to send a UDP packet and all have to wait.
If this is what's going on, then moving the siptrace server to a
different subnet should resolve the problem.

Hi,
I have the exact same configuration with two workers and same syntax.
It works fine until I shut down homer. After that Kamailio stop
precessing any traffic and all clients try to register as they are
disconnected.
Kind Regards,

Hi,
try to define an extra sendsocket.
And add an listen directive for that sendsocket. Sorry for

Works for me with an similar setup and 5.3

Hi,
Memory on the system is 8GB and on Kamailio we have SHM
4096 and PKG 32. Each of these VM handles only a few
hundred of concurrent calls and each VM has a few hundred
of TLS user registrations.
Kamailio uses IP to send the traffic to Homer and not
domain name.
Any ideas how to solve this issue?
Kind Regards,
Angelo

Hello,
Interesting observation. Do you see anything
related to this error period in the log files?
Maybe out of memory errors etc..?
Cheers,

Hi to all,
We have a Kamailio 5.3 that sends all traffic
to a homer7 using siptrace module with
parameters force_send_sock and hep_mode_on,1
and hep_version,3 and trace_mode,1. Everything
works fine getting all traffic to Homer7 but,
in case Homer7 is not reachable, Kamailio then
no longer accepts traffic or registrations and
it is like it crashes. When we revive Homer7
and is it again reachable accepting traffic,
Kamailio then works again fine without any
restart or actions.
Any ideas why this may be happening? Is there
anything we need to add to the config to avoid
this behavior as having Homer7 now is a single
point of failure for Kamailio?
Thank you!
Kind Regards,
Angelo
