[Asterisk-Users] Asterisk freezing HELP

[mattf]

Hello,

I have had several instances over the last month of Asterisk freezing,
sometimes after 12 hours, sometimes after 8 days. The common elements are
that:
- all Zap channels lock[hangups don't register and no new calls in or out]
- no new in/outbound calls can be made on Zap or SIP channels
- people who are still connected to calls can continue to talk
- in the CLI interface, you can "show channels" and view other info like
"sip show peers", but you cannot do a "stop now" only way to stop asterisk
process is a kill -9
- all attempted connections to the manager interface time out
- the processor load and RAM usage on the machine is low.

I am experiencing these freezes on two separate identical RedHat 9 machines.
On each I have 4 T1s connected and a usual concurrent call volume of 45
Zap/SIP conversations at once 14 hours a day. The processor load is never
that high and the RAM usage is less than half.

There are never any consistent errors or warnings in the logs or the CLI.

I do have several AGI perl scripts in the dialplan and the SIP phones that
connect are almost all Grandstream 102's, That's all I can think of that may
be causing any problems. I have mpg123/musiconhold deactivated.

Has this happened to anyone else out there?

Does anyone have any suggestions? or ideas as to what may be causing it?

Thanks for any help,

MATT---
