Hi,
I have been doing some load testing on kamailio 5.4.7 running in podman.
Kamailio is using dmq to share dialogs and htable with a backup Kamailio also running 5.4.7.
I tested with 100 CPS and during the first minutes all calls are being processed correctly but then all the messages start to be retransmitted.
Kamailio is not processing any sip messages anymore but still replies to HTTP requests, is still possible to run kamctl/kamcmd commands on it but for example, if running the command "kamcmd dlg.list" nothing happens.
Also, I did a load test with the backup Kamailio turn off so that there is no replication between them, and in that case, I can run the 100 CPS without any issue.
In kamcmd trap file I can see a lot of "<error: Cannot access memory" errors.
In order for Kamailio to start processing again sip, I need to restart it.
Any extra logs that I can try to collect when the problem happens?
