    Hi,

    I have been having a fairly serious problem with an HP Netserver LH3
    that seems to hang for no apparent reason. This happens when the
    machine is under load and it also happens when it is simply idle. When
    this "hang" occurs I can no longer SSH to the box. I can ping it and
    port scan it and it appears to be "alive" but it won't load web pages or
    process mail etc. When I physically access the box there are NO error
    messages, warnings or anything on the monitor and when I attempt to log
    on, I enter any username or root and hit enter and it just sits there
    forever. I try Ctrl + ALT + F2 and I have the same problem on another tty.

    When I power off and then log on, I am unable to find any evidence of
    what is causing this problem in any system logs.

    I am wondering if is because I uncomment the 2 lines needed for SMP
    support, and rebuilt 4.8-STABLE FreeBSD and boot to that kernel. I do
    this because I would like to use both CPUs. I suppose I could do that
    and then run it and see if that is in fact the cause but that would not
    really get me any close to using both CPUs which is of course my
    ultimate goal.

    I am about out of ideas here, what should I do first?

    Thanks!

    Rick Up

    P.S. Some hopefully useful info can be found here:

    dmesg @ http://12.246.251.12/dmesg.txt

    SMP kernel config file @ http://12.246.251.12/SMP.txt

    var/log/messages @ http://12.246.251.12/messages.txt

    I am running qmail + vpopmail + procmail under a very light load 1000
    messages per 24 hours right now and apache with almost no load at all,
    just me reading documentation etc.
