I was hoping someone may be able to help with my issue, which I have so far been unable to resolve.
We have been running Asterisk 22.214.171.124 in production for some time now, on Centos 5.6 (32bit) machines, without any issues whatsoever.
We are now trying to swap them out with some new machines, running Centos 6.4 (64bit), Asterisk 1.8.15-cert2, same config/dialplan etc. However, randomly, after a period of no load, Asterisk stops processing SIP calls yet the CLI and manager interface are both fully responsive.
When it happens, the command “netstat -anp |grep 5070” (the port we are listening on) shows lots of packets queued waiting to be processed.
Then, all of a sudden, after 10-15 mins or so, Asterisk springs back into life and the queued messages are processed.
I have the output of “core show locks” and also a backtrace but can’t see a way to attach files here - I can provide links to them if required.
I hope someone has some experience of a similar issue, as I am just about running out of ideas
Many thanks in advance,
