I am having an issue with Asterisk 11.18.0 where after a certain amount of queue calls (I would say about 40), the system stops responding to inbound calls. It doesn’t actually ever crash but I can see many locks (Core show locks) in the system. Some are related to mysql. I have an external system that is querying the database and it never stops functioning therefore I don’t believe it is a mysql issue.
The only errors I can see in the log are:
htop and top show only 20% cpu usage during the occurrence of the issue and RAM does not seem to be an issue either.
Running Centos 6.8 32bit. 8GB RAM (PAE). Quad Core processor with HT x5550 2.67Ghz.
Any suggestions? What else can I use to troubleshoot?
