We have a SharePoint 2013 on-prem farn, with 2 Front End and 2 Application servers. The User Profile services run on the application servers. We experience every day that the "User Profile Synchornization Service" goes down and gets the status "stopped" on one of the servers. Which leads me to this question, can the "User Profile Synchronization Service" run on 2 servers, in our case 2 application servers, in a farm?
It would be strange if it couldn't, but I am asking this because I am not finding any logical reason for why this happens.
In my experience this service has been very unstable. Any body else that share my experience ?
