freebsd on multiprocessor system

[Aleks]

Hello everybody.

I'm going to use a system based on two Pentium II (two) processors.
What version of freebsd can really work on this system?
I have heard freebsd work for couple of days and then crashes.
My multiprocessor system will be act as a web server and file sharing server
with critical data on my intranet with 30-50 users. Can I use freebsd on
such system?

Thank you and pardon me for my English :)
