[Asterisk-Users] System Hang Problem

[Darren Sessions]

I am getting some weird behavior and a rash of interesting messages in 
the log files. If anyone has some ideas, it would be appreciated.

Using Asterisk v1.0.1 on Suse Enterprise Linux v8.0. HP DL380 Server. 
4GB Ram - Dual 3.2ghz processors.

This first entry is when asterisk simply goes unresponsive. We've got a 
script that automatically polls asterisk (via sip) and restarts it if 
it does not receive a response. Notice the 9:56 to 10:01 gap.

We've started getting allot of these messages in our log files. 
Unlikely that this is not associated with the first problem.
