    After enablling all cron jobs except "updatedb" the site still went down. I may try to force the crons tonight one by one to see what is causing this. The ones I have running are:

    00-logwatch
    chkrootkit
    freshclam
    logrotate
    prelink
    squirrelmail.cron
    tmpwatch
    certwatch
    clean.quarantine
    fw
    makewhatis.cron
    rpm
    tetex.cron
    tripwire-check

    Is anyone else experiencing any issues and running close to this same cron daily setup?

    Well...the update is...I turned off the backups and all daily cron jobs last night (besides logrotate. The site didn't go down thank God! Now I just have to add backups back tonight, see what it does. Then add the cron jobs back (excluding the updatedb to start just in case). Does anyone know why all of a sudden, if it is updatedb, that it would start affecting my forum like it has when it hasn't before?

    The only thing that baffles me about it is I don't recall anything changing with that 6-7 days ago. It's always run on a daily cron since I've had the server so the weird part is why is it only now causing issues (if it is indeed the cause which we'll find out about 4 hours from now bleh!).

    I have it disabled for tonight so we shall see...<crosses fingers>

    It would appear that this is your cause:

    It appears that what started up around the same time the site stalled out is the "updatedb" command.

    Tonight I am going to try and turn off all daily cron jobs as well as all backups on the server in case something there is causing this. Is there any kind of individual log that VB can create that is up to the minute on what's going on or what may cause it to goof at any given time? (besides the standard access_log/error_log/messages in Apache)

    Ok...so the sixth (seventh, I lost count!) morning in a row now the site has stalled out. I just stayed up watching some God awfully boring TOP commands to see what exactly is happening around the time the site goes down. It appears that what started up around the same time the site stalled out is the "updatedb" command. I am on cpanel/WHM. I've never had this issue before 6-7 days ago and I have been running this forum on my server since around March of 2004. Is anyone else out there experiencing issues with this or know why this may cause my one VB forum to go down but not others? Other commands that were running were gzip/tar as part of some backups that were running. I turned off backups on this particular account though so I could try and rule that out. When this happened I stopped/killed all httpd/mysql instances. Then I restarted, and that still didn't work. Still requires a complete server reboot to snap the forum out of it stalled state. Then it is perfectly fine all day until this time in the morning again. Am I going crazy here? Must get some sleep now...

    Its possible some sort of backup script is locking the MySQL tables and that makes it seem like the site is down?

    Are you sure (serious response). I would tend to agree with you if ALL my sites were down and not just this one.

    This is a server issue. For help with optimizing your server, please see this thread:

    http://www.vbulletin.com/forum/showt...threadid=70117

    Then post the requested info in a new thread in that forum.

    Well I'm at five mornings in a row now. I had turned off cpanel backup thinking maybe that was causing the site to stall but to no avail. I actually got up at 5am to make sure the site was online or not and it was. Seems around 5:38ish it stalled out again though. This is weird...I can pinpoint the time within like 15-20 minute range but the error logs don't really reveal anything to me, access_log either. I can't for the life of me figure out what may be causing this.

    4 mornings in a row now grrrr. One time it did eventually come up but took like 10 minutes. Another time 10 minute it wasn't working. In WHM the MySQL processes for the site just kept building. I turned search off for the site so noone could have run that could they, some sneaky way or something?

    Any other suggestions besides turning off search while I sleep? I am about to go into the time here where it could go down while I sleep and I am fearing I may start losing clients (I charge for forums on my site). Any help appreciated. (Is that query issue a known hack/bug?)

    Ok I have turned on debug mode...but reading your reply now I don't think this will help me because:

    1) you are saying to do this on the page that is slow...but ALL pages I try are doing the same thing, not just one. So it's not one particular page.

    2) I am not able to get the paged to even come up when the issue is happening so that I can see the debug footer.

    If I turn off the search feature before I go to bed would that tell me if this is a long query issue? (If I wake up to find my site is fine and responsive).

    Let me also clarify that whatever is happening is happening whle I am asleep... I was up to like 3 am last night (EST) and checked it at 9:45 when I woke up and it was like this. I'm not quite sure what I would look for in the log files to troubleshoot this. One thing I DID get this morning and also on the first day this was happening is this via email (part of the batch I always get when the server is rebooted):

    Database error in vBulletin :

    Link-ID == false, connect failed
    mysql error:

    mysql error number: 0

    Only difference is the ip address and id#. I am going to sign up for this site so I can see what this referring link leads to. I don't know if it is nothing or not. It's probably just someone with a link to my site in their signature or something.

    Sounds like a hack is installed that causes long queries perhaps.
    Turn the vbulletin forum in debug mode and load the page that is very slow in explain (to be found in footer) and see which queries are fast and when it starts to crumble to a stop.
