Dear All My CentOS server got hung and when I tried to power cycle it , I checked its /var/log/messages & /var/log/dmesg with respect to the time of fault occurance to see what was really happened . But its 'messages' log does not show anything recorded for about 30 minutes before its recovery after power cycling . Can you please let me know where I can check to find the root cause of failure ? Thank you -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.centos.org/pipermail/centos/attachments/20100222/e3bc0f5a/attachment-0003.html>
