Memory Critical

Hi,
i’m checking 3 same ESXI Servers with the plugin.
With 2 Servers all is OK.
The third Server is giving me a Memory Critical, I checked the Server Memory and all the Memory is okay there is no failure.

I think the problem is here:

Check classe CIM_Memory
20160713 11:00:09 Element Name = Socket 1 Level-1 Cache
20160713 11:00:09 Element Op Status = 0
20160713 11:00:09 Element Name = Socket 1 Level-2 Cache
20160713 11:00:09 Element Op Status = 0
20160713 11:00:09 Element Name = Socket 1 Level-3 Cache
20160713 11:00:09 Element Op Status = 0
20160713 11:00:09 Element Name = Socket 2 Level-1 Cache
20160713 11:00:09 Element Op Status = 0
20160713 11:00:09 Element Name = Socket 2 Level-2 Cache
20160713 11:00:09 Element Op Status = 0
20160713 11:00:09 Element Name = Socket 2 Level-3 Cache
20160713 11:00:09 Element Op Status = 0
20160713 11:00:09 Element Name = Memory
20160713 11:00:09 Element Op Status = 6
20160713 11:00:09 Global exit set to CRITICAL

If I comment out “CIM_Memory” then the plugin shows “OK”, but thats no solution because I want to monitor the memory.

Can anyone help me please?
