Hello All,
This is my first post on the forums so please bear with me. We have two datacenter in vCenter which are separate. One is in NJ and the other is in FL. Anyway, the hosts I am discussing here are running ESX 4.0 with the exception of one host which is running 4.1. Lately, we have been getting memory alerts built into vSphere. They are the default alerts. We have not changed any of the criteria of these alerts or whate triggers them.
Anyway, we were receiving complaints from users about certain VMs being slow. When I investiged using ESXTOP, I saw that one of the hosts was swapping fairly heavily. I did not expect to see this at all since the ESX host the VM was on had plenty of free memory (we are talking over 20GB). It was also in the high mem free state. We have no reservations or limits setup in our resource pools or anything which I can think of which could cause. I am attaching an image file which is a direct copy from the ESXTOP window. Why is there swapping with the amount of free memory available?
Thanks.
