Hello there!
I am running into issues when FreePBX is under some load (25~50 simultaneous calls) and reload is performed (Apply config button in web interface). Sometimes (once per 2-4 weeks) asterisk got stucked in weird way, when any action or call can me done, but ended calls are not inserted into CDR database, and channels are not hanged up at all.
Asterisk seems to be trying autodestruct channels with no success until it’s restarted (CLI> core restart now). I tried to shoot down channels manually, unfortunately I wasn’t lucky with any CLI command I tried.

I have already seen this message when MySQL database was under quite a load and query insert into CDR took about 8 secs (it’s due to some custom modification - triggers and generated reports) but in this case warning occurs just once or twice. When problem is triggered by config reload, warnings are increasingly spamming log and no more CDR record is saved into database.
To me it seems there is some race condition causing deadlock in asterisk core or CDR plugin, but unfortunately I am not able to inspect source code. Issues began when number of simultaneous calls exceeded 15~20 calls and I didn’t find any pattern of occurrence.
We found this issue in FreePBX version 1.814.210.58-1, but after upgrade to 1.818.210.58-1 is was OK for about 3 weeks but yesterday it returned.
I am now clueless and will be happy for any help or idea.
