On some machines ZenUserDaemon.exe is using all available memory. The
process starts allocation memory after the Zenworks login has occurred and
eventually allocates all available memory and makes the computer unusable.

This is only occurring on some machines some of the time and it's usually
fixed by rebooting the computer, but not in all cases. Of course the
problem shouldn't be occurring at all. The problem has occurred on Zenworks
11, 11 SP1 and 11 SP1a.

The machines on which this problem is currently occurring are running
Windows 7 Enterprise 64-bit SP1
