Have a nw6 sp5 server running on a physical box. It doesn't do much of
anything aside from edir things, ldap authentication, timesync, & has
Sophos sweep on it.

It runs for a few days, and then cpu util goes thru the roof, anything
that needs this server for ldap, whatnot quits working. When checking
the busiest kernel threads on this box the last time it happened, the
busiest thread was called Server 01:85, and had a value of over 3.1
million microseconds in a 3 second poll of the cpu.

Any ideas what could be causing the server process to spike like this?
