>Description:
Server for mass hosting with 1000 sites on it freezes every 8 hours at
the average. No kritical error occurs, no messages. If the server remains
unloaded, it's works fine. We've excluded all possible problems with
hardware as the problem persists on different servers from different
vendors. We've examined FreeBSD 6.5 (32 bit), FreeBSD 7.2 (64 bit) and
FreeBSD 8.0 (64 bit) and only 64-bit versions are believed to make the
server freezed.

Hosting Center is the second largest hosting provider in Russia. We run
over a hundred servers for mass hosting under FreeBSD and until now
there was no other problem like this one. We would be very grateful for
any help from FreeBSD developers team.

 So don't you want to show "pfctl -sa", for example? Moreover, current
 additional information doesn't enough - could you provide crashdump, if
 it exist?
 Take a look also at /usr/sbin/crashinfo, it gives you a hint for some
 diagnostics utils.
