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.

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

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,
Do use domain name as destination for homer?

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

Any ideas on this topic?
Anyone with same behavior?

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
