Known Issue: If you are on a currently using Cumulative Update for SQL Server 2014 and need to use TLS 1.2 for encrypted endpoints for features like Availability Groups, Database Mirroring or Service Broker, then we recommend that you wait till the next Cumulative Update for SQL Server 2014 (February 2016) which adds support for this particular scenario. This is documented as a known issue in KB3135852. All the other branches mentioned in KB3135244 have support for this scenario.

Please feel free to post your questions and comments.

    If the SQL Server instance is facing intermittent service termination after applying KB 3135244 please refer to KB3146034.
