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></div></div></body></html>
