[SR-Users] Re: Sudden TCP errors and shared memory spikes

2024-04-29 Thread David Cunningham via sr-users 
Hi Henning,

Thank you for that. I was not sure what direction to take traces in, so
possible network issues with clients using TCP is a good indicator. We'll
look into that.

[SR-Users] Re: Sudden TCP errors and shared memory spikes

2024-04-29 Thread Henning Westerholt via sr-users 
Hello,

if Kamailio can’t send out messages due to network issues I would expect some 
spikes in private and/or shared memory usage.

Have you investigated e.g., with some traces to get more information about the 
possible causes of this issues?

Besides that, with the given information I can only recommend the usual update 
to the latest stable version (e.g. 5.8.1) as the 5.2.x release series is long 
end of life.

Cheers,

Henning

Subject: [SR-Users] Sudden TCP errors and shared memory spikes

Hello,

We have a production Kamailio 5.2.7 server which has suddenly started reporting 
spikes in the shared memory use. When looking into this, we noticed that at the 
same time as the memory spikes Kamailio also logs a huge amount of errors like 
the following.

Can anyone help with an explanation for what's going on? The xx.xx.52.202 
address is the Kamailio server itself. We record historical numbers of network 
connections for the server overall, and that doesn't show any increase in the 
number of TCP connections, either at the time of the spikes or as a general 
trend.

Thanks in advance!
