    NETWARE 4.1 HIGH PROCESSOR UTILIZATION WITH DPTCOM.NLM

    This is an informational bulletin.

    CONDITION

    After loading the DPTCOM.NLM support for the DPT PM/3224 SCSI RAID
    Controller, under Novell Netware 4.1, the Novell MONITOR will show
    processor utilization between 50% and 100%.

    OBSERVATIONS

    This is a normal condition with the DPTCOM.NLM support for the DPT PM/3224
    RAID controller.  As soon as any driver or NLM requests services from the DPT
    controller, the processor utilization will back off to a normal range.
    This condition does not present any performance degradation or problems with
    the server.  The condition does not occur with Novell Netware 3.X.
