    I am not sure where to start to track down this problem.
    After a while (different each time) server stops responding.
    I am unable to ping or shell into box to see what is up.
    I hard reset box and all works ok then a few days or few hours later it stops responding again!! What logs should I look at or how should I track this to correct?
    Please advise.
    thanks in advance.
    ubuntu perfect server 10.10 ispconfig setup
    installed about 1 month ago...

    I suggest you install munin. It might help you track down the problem.
    Sounds like a problem with your memory or swap.

    server stopped again

    log from when it died to after restart
    Muni didnt really show anything just that it went to sleep and stopped too.
    Could this be a power saving issue ? how to turn that off?
    Thanks.. ps doesnt appear to be using swap at all

    Are there any spikes in memory or CPU usage?
    Is this a physical server or a virtual machine?

    To me it looks as if this is related to your hard drive. You have spikes in the Disk Latency (= long I/O wait) and the IO Service Time graphs which (I guess) makes your server hang.

    new drive installed swap still not working

    Ok, keep fingers crossed that new drive does it for me.

    How do I get the swap file to work again?
    thanks----

    Do you get any errors? Is it listed in /etc/fstab? What's the output of
    Code:
    mount
    ?
