I got this in the "memory" column for a Solaris 8 host this morning, which caused it to go red (even though i have the threshold set to 101).
Thu Aug 3 09:11:17 BST 2006 - Memory CRITICAL Memory Used Total Percentage red Physical 4294955003M 131072M 4294967287% green Swap 40973M 144024M 28%
That physical memory calculation is obviously incorrect!
This only happened once, then it went back to normal. The "hostdata" that was saved at the time of the alert had the following memory data:
[memory] 0 0 0 211046168 146806184 744 6249 0 0 0 0 0 0 0 0 0 2692 436955 11454 8 6 86
That looks fine to me. I can't see how it could have taken those values and got that bizzare total for memory.
This is how it normally looks for this host:
Thu Aug 3 10:01:48 BST 2006 - Memory OK
Memory Used Total Percentage green Physical 59483M 131072M 45% green Swap 40960M 144026M 28%
and this is a sample of "normal" memory data from the host:
[memory] 0 0 0 105535000 73280352 152 910 0 126 126 0 0 0 0 0 0 3339 811798 11953 4 7 89
(I'm running 4.2-RC-20060712)
