    3 of my servers has it Server load going every weekday on some part of the day to 150.00 or more, Why?

    Goes like this:

    the server is working normally, and for no reason that I can see the server load goes to 150 so I need to reboot the server and got normal again.


    Does anyone is having this problem, is there any solution ?

    Thanks

    what does top say the heaviest processes are at the time? Also check your dmesg for faults there.
