CheckCounter returns wrong result for periods of time

[DonaldGordon]

I've noticed that performance counters I'm monitoring with CheckCounter will sometime return the wrong result for a fairly long period of time (usually 8-12 hours).

Looking at the graphs from PNP4Nagios, my .NET heap stats (counter .NET CLR Memory(_Global_)\# Bytes in all Heaps) over the last week on one host have a few 8-12 hour periods where they drop from the normal value (>1GB) to something clearly wrong (10-20MB). This either comes right by itself, or when we manually restart nsclient. I've only seen one host do this so far, and only on the .NET heap size counters.

Could you check the actual values? perhaps there is some unit which is miss interpreted by pnp4nagios?
