Server Crashes After Backup Setup

    Hello,

    I have a problem with my WHM setup that I think is related to my trying to create a Backup.

    In WHM I setup a backup to run and I guess it might have failed. The entire server was taken offline and I had to have my NOC manually restart it because I could not even SSH to the box. Is this something that a WHM crash is capable of?

    To undo the error, I tried resetting the backup configuration back to the box defaults. Does setting the Backup Status to "Disabled" effectively kill the backup process? Is there anything I need to change that may cause the server to die?

    Thanks!

    The server is a P4 3.06Ghz
    1 GB RAM
    WHM 10.0.0 cPanel 10.0.0-C40
    FreeBSD 5.3-RELEASE i386 - WHM X v3.1.0

    Same for me.

    Just crashed after I did setup the backup feature.

    Still waitting for my datacenter to find a solution as i can not ssh anymore.

    Normal or my fault or ?

    My resolution

    My resolution will not help you much... I had to have the server chassis replaced!

    The datacenter took my /home drive and moved it to another machine, and now things seem to be working properly...

    You might have backed up in /home and it used all the server disk space or you did not specify where to backup and it did backup on /root which does not have much space ..

    I have had the problem last night with WHM 9.9.9 cPanel 9.9.9-S15.

    The server didn't crash and still was pingable, but nothing responded anymore. I had to reboot and the server came up fine. This was the last:

    ravand, it was a fresh cpanel install there was no reason for a partition to be full.

    Thanks for your suggestion,
    Best regards,
    Francois

    this all looks really familier. If your running 2.4 kernel thats prolly going to be your problem. Upgrade to the 2.6 kernel either using fedora or a custon 2.6 kernel
