<br>
I'm experiencing a lot of server freezes lately. The server just...
freezes.<br>
<br>
I notice in the log files (/var/log/asterisk/messages &
/var/log/messages) that logging stops at the time the server hangs.
Logging continues when the server has been restarted (which is the only
solution).<br>
<br>
So it is not a proces that hangs, it's the entire server (CentOS5.5 +
Asterisk + MySQL).<br>
<br>
I really have no idea what can be causing these sudden freezes. Memory
stays mostly at 250MB of 512 MB total, CPU is 97% to 100% idle...<br>
<br>
/var/log/asterisk/debug tells me nothing, no lines that indicate
something strange before the freeze (debug level 9).<br>
<br>
I have no core.pid file in /tmp, when I look after rebooting the server.<br>
<br>
The only thing I have is a high level of mentionning of "kernel: dahdi:
Detected time shift." in /var/log/messages.<br>
<br>
<br>
What is causing this kernel message ? Could this be the cause of the
server freeze ?<br>
<br>
Thank you for every feedback you can give me.<br>
<br>
<br>
Kind regards,<br>
Jonas.<br>
