Correlated with the fact that there is less than 20MB of memory to allocate, it appears that you don't have adequate memory for the workloads you have.

I have PMP running on five servers and every one of them generates this alert at least 5 times a week. Three of the servers have a very low load on them and no "strange" software installed. When reviewing the playback of the performance data it always shows up as a single spike in the graphs. I am more inclined to think that this is either a bug in PMP or an hp driver or agent. I cannot reliably send out performance alerts because I get so many of these, and they don't appear to be valid. Just my 2 cents. :) Fri, 04 Feb 2005 11:06:13 GMT https://community.hpe.com/t5/server-management-systems/sim-4-2-pmp-reports-memory-events/m-p/3473917#M9467 Brent Neste 2005-02-04T11:06:13Z https://community.hpe.com/t5/server-management-systems/sim-4-2-pmp-reports-memory-events/m-p/3473918#M9468 Spikes in Page usage are caused when an application places a demand for additional memory. Pages are faulted in and the process continues.<BR />In some instances the process could be re-engineered to pre-allocate memory, thereby not having the spikes as it allocates and then sheds memory.<BR />I agree it does seem a bit sensitive at times, but disagree that it's a bug.
