RE: Priority and CPU usage of Domino Services

Nathan,

Yes, this sounds like fairly normal Domino behavior.  Batch jobs will try
to consume whatever resources are needed in order to accomplish their
job.  Having a job periodically wake up and do some intense work should
not be considered a problem unless your system is approaching CPU
capacity.

If your system is approaching 100% CPU utilization and the Domino jobs
push you over the edge to the point where interactive users (or other
critical jobs) experience prolonged response times, then you have a
problem.  Are you there?
