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.
