[xymon] Xymon reports excessive memory usage on 1 SLES 11 host

[Tim McCloskey]

I've seen the same strange reports from 4.2.0.  Solaris 10 zones on x86 are the reporting clients, example: 
red Physical     4294953114M      16384M 4294967210%

Since it's not a large scale issue for me I've not dedicated any time to looking into it.  For me,  it's a new issue on recent zone deployments only (in the last year or so), so I figured some version of shell tool xyz may be the culprit.  I can look further or provide additional data if needed.  The point is that from 4.2.0 to 4.4 the issue presents itself, but it's new for me so I'm not sure it's hobbit.

Regards, 

Tim

Here are two separate [free] sections (from history), that resulted in red alerts:

Im actually running 4.4.0-1 on the server, as I was bold when I implemented Xymon originally.
