Now that I've disabled SMP there are no problems, and the same tests are working perfectly... The only thing I've changed is the SMP support, and now its been running = for 4 days, before it wouldn't run for 12 hours Thanks Dave -----Original Message----- From: Albert Shih [mailto:shih@math.jussieu.fr]=20 Sent: 04 June 2004 01:47 PM To: Dave Raven Cc: freebsd-questions@freebsd.org Subject: Re: 5.2.1 SMP problems Le 04/06/2004 =E0 11:47:14+0200, Dave Raven a =E9crit > Hi all, > Installed 5.2.1 on a high load server - albeit not recommended - = and=20 > it was working perfectly with SMP support.

First check your memory with some software like memtest86 (http://www.memtest86.com/) When I've this kind of problem, always it's because some error in RAM.
