I upgraded my web server to 2.2.5 from 2.2.2-stable, dated sometime in
July.  

Big mistake.

The only update to take place was the make buildworld, make installworld,
no other configuration files were modified, nor any changes to startup
scripts, etc.

I now get these weird pauses where everything on the machine just freezes
for 30-40 seconds, sometimes longer.  NFS is compiled in, but not in use.

The system was a web server, and was happily serving up several hundred
domains.  Now with the upgrade, I'll be lucky to keep them.  Not good.

It's a Super Micro P6, 384MB RAM, 2 SCSI disks off a bus-logic controller.

Any ideas appreciated.  I have built a new kernel from sources supped
11/7, but it doesn't seem to be any better.
