RAMMap - Issue running it on SQL server

Question

I recently ran RAMMap on an SQL server that was the current owner of the availability group in our failover cluster. When the utility was run, after some time, all availability groups that this particular node was the owner of went offline and would not allow us to failover to any other node.

I did my due diligence and read the documentation beforehand and did not get any indication that running this program would cause any issues.

My question here is has anyone else had this issue? Is it a known issue and if so, what is the cause?

FWIW, I was running RAMMap to troubleshoot an issue where copying our SQL backup files was taking a long time. I suspected the cache was filling up which was causing the slow transfer speeds.

Any help or insight is greatly appreciated.
