Server NW 6.5 with SP5 applied 23 Jan 2006

ZenWorks Suite 6.5
ARCserve 11.1

Server HP Proliant ML350 4GB RAM - P4 Intel Xeon CPU 2.80GHz -
Hyperthreading disabled in BIOS

I have remmed out of AUTOEXEC.NCF the startup for ARCserve and ZENworks,
but it seems to have made no difference.

About 2 weeks agao the server started abending about 1 or twice a day.

I'm not sure as to how much of the abend log to post, as these are the last
7 abends:

The problems seemed to really start after I tried to used Hamish's memcalc.
I have since # out all the recommended mods (I had marked the section of the
script with mods) but it has not made any difference.

Help as would be greately appreiciated especially as my manager would
delight in any reason to switch to Windows Server!!!
