[Xymon] xymon disk not alerting at 100%, need another set of eyes

Eyeballing it, it seems to be correct, and if windows matches are 
working then it seems like class (or at least OS) is being sensed 
properly. Can you put xymond_client in debug mode (-USR2) and show the 
output from the processing of the disk section for this client? It 
should indicate there the thresholds it *thinks* apply to this host.

Also, when running manually like this:
     /usr/libexec/xymon/xymond_client --dump-config
...can you prefix with xymoncmd and see if anything changes? Weird 
configs I'd forgotten about in xymonserver.cfg have bit me on occasion.
