I configured mirroring for 33 databases in an instance. Recently the mirroring failed and I found many network related errors like:
- Database mirroring connection error 4 '64(The specified network name is no longer available.)
- The Security System detected an authentication error for the server MSSQLSvc/servername:port. The failure code from authentication protocol Kerberos was "There are currently no logon servers available to service the logon request.
Mirroring timeout for each database is either 10 or 30 seconds.
