I'm getting these error message every other week or so!  The mirror is configured on Windows Server 2008 R2 Enterprise edition with Active/Active Cluster setting!

Error Msg: Database mirroring connection error 4 'An error occurred while receiving data: '121(The semaphore timeout period has expired.)'.' for 'TCP://Servername:5022'.

The SQL Server Installation Wizard provides a single feature tree for upgrade of SQL Server components.
You can also install SQL Server 2008 R2 side by side with an earlier version, or migrate existing databases and configuration settings from an earlier SQL Server version, and apply them to an instance of SQL Server 2008 R2.

Since principal server keep on sending logs to mirror server every 60 sec, for each interval if transaction doesn't get committed to mirror server completely then the witness starting sending error stating Mirror Session are not syncing.  Basically, it was network latency issue with the witness server.
