Server components states keep getting marked at inactive

I have a new Exchange 2013 server on premisses.  Twice in the last week some of the server components have been marked as inactive.  Is there a way ti figure out why this is happening?

This is randomly stopping mail flow from our ticket tracking software because it uses POP3

These are the commands I had to run before.  I will correct this IMAP proxy one in just a bit;

Set-ServerComponentState -Identity lo-exch2 -Component imapproxy -Requester HealthAPI -State Active

Set-ServerComponentState -Identity lo-exch2 -Component forwardsyncdaemon -Requester HealthAPI -State Active

Set-ServerComponentState -Identity lo-exch2 -Component PopProxy -Requester HealthAPI -State Active

Set-ServerComponentState -Identity lo-exch2 -Component provisioningrps -Requester HealthAPI -State Active
