RE: Priority and CPU usage of Domino Services

["Andy Nolen-Parkhouse" <aparkhouse@xxxxxxxxxxx>]

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?
