Unfortunately the machine freezes completely and I can't break to the 
debugger anymore. It happens absolutely unforeseen, therefore I can't 
examine states shortly before it freezes. I run several instances of 
'unixbench shell' and 'ubench -c'; sometimes it takes a few seconds and 
sometimes 10 minutes until the machine stops working.

I like to except hardware failures, because FreeBSD 4.11 and Windows 
Server 2003 run under high load without problems for several hours.

I'll spend some more time.
