No, that would make it crash ;)

You might however, have a bad disk, if processes are getting hung up
trying to read a block on the disk, the running process count will grow,
but the machine won't actually be doing anything, this will give you a
high load average, but a mostly idle cpu usage. Processes waiting on
network connections will do this too, a bad cgi script, a mail config
problem....you need to be poking about in the logs for *anything* weird...
(Especially apache errors and complaints about dead children etc)

running badblocks may be a good idea....

gsh
