<font face="Helvetica, Arial, sans-serif">Hello.<br>
<br>
Thank you for the feedback.<br>
<br>
To reply to all the information :<br>
<br>
@ Shaun Ruffell : What do you mean by Wall time ?<br>
This server is indeed also time server (ntpd is running)<br>
<br>
@ Mark Deneen : No, no monitor attached. This is a Xen VPS. I do have a
VPS interface, but this is also frozen when the server hangs...<br>
<br>
@ William Stillwell : I run Asterisk 1.6.2.10 with Dahdi 2.4.0 (as
timing source). Time on my server seems very consistent. When doing
/usr/sbin/ntpdate (once a month) there is a very very small offset.<br>
<br>
<br>
Kind regards,<br>
Jonas.<br>

<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.</span><o:p></o:p></p>
