Running Apache on multiprocessor system

Hi all

I have problems with running Apache 2.0.35 in a Windows multiprocessor
system.

The problem is, that sometimes the service hang up and doesn't
responds anymore. I have to kill the service and restart the server.
On a single processor system I have nerver seen such behavior.
Looking thru the net shows me contradictory information about running
apache on multiprocessor system.

Does anybody have the same situation running an apache server on such
a system and can share some experiance?
Do you have had such problems and solved it by upgrading the Apache
server to a newer version?

Thanks for any help
