Thanks for the detailed information Gail.

instance1 is using 1.42GB out of 6GB and instance2 is using 554 MB out of 6GB.

But one thing I did not understand is, 2 the instances never went to their max memory and there are no other application running other then these two instances. 4 GB is left for OS. So where is the memory pressure:crying:

But all of sudden after setting Min memory to 1GB, I'm not seeing PLE and CPU issue.

Need to investigate more. I will try setting min memory to zero and see if the problem comes back.

This is 2-node active/passive cluster. 2 instances are on the same node
