I need decrease traffic in my server, I have 6000 endpoints and many times the PJSIP stop to response .
The load of server its ok, the CPU keep between 30 - 50%
I used Asterisk 18.4.0 and I have others problems with crash, the last week I open issue in jira with all logs and backtraces.
Now I used 16.8-cert im my servers and the crashs decrease.
About this ticket I put minimum_expiration and the asterisk answered correctly , I will make a tests for try solve the problem about “pjsip stop to work response”.
I think if I decrease traffic in PJSIP would work.
