Alarm Profiler Queue Size Limit Reached" or "Insufficient Virtual Mac

[Amen]

we have an issue  For unknown reasons some of our virtual hosted ISE nodes based on VMware are getting overloaded each day at the same time. We checked all we could and there is nothing that is supposed to cause this on the VM itself. There is no backup job running for these specific nodes. It is connected only to three specific nodes we have in North America. Overload causes alarms like "Profiler Queue Size Limit Reached" and "Insufficient Virtual Machine Resources".

is there any BUG known?

This indicates a couple things, the storage you're running ISE on is not fast enough, and the number of profiler syslogs coming in are overrunning the queue. 

If the storage is falling below the thresholds this can also cause the profiler queue to backup as messages are not ingested to the database fast enough. I would be looking to sort the hosting environment around that time since both messages are occurring simultaneously. If the profiler queue alarms are occurring at all times of the day that could also indicate that these two problems are indirectly correlated and that you have too much profiler load for the deployment.
