Has anyone seen this error before on 11.1a

.NET Runtime 2.0

EventType clr20r3, P1 zenworkswindowsservice.exe, P2, P3 4e5f8ee2, P4 mscorlib, P5, P6 4ef6c16f, P7 15c, P8 51, P9 system.argumentoutofrange, P10 NIL.

ZCM service falls over and stops you then have to start it again.....

I know its to do with the ZESM client cause we do not have it on our 10.3.1 clients which are the majority of the estate. I been given the latest ZESM client built that in to my image and low and behold.. same thing...

We have the following clients that affect the network, Lumension Sanctuary, Trend OfficeScan 10.5.1997

PCan anyone offer any advice

I've got an SR but I cannot manage to get a minidump of this so have had no help.
