We have 2 servers running exchange 2013 which are in a DAG setup.
For the past week or so, every once in a while the active server will fail the dbs over to the passive node. I don't see anything in the event viewer to indicate what the issue maybe. Not sure if it is a network issue or what but once I see it has failed over, I just fail it back and then it is good again for some time.
Any suggestions on what I can check for this issue?
