SQL Server 2014 SP2: SQL Server is not ready to accept new client connections

  • Hello,

    Today morning we noticed that our SQL Server started crashing and noticed the below error from Event Log / SQL Error Log:

    SQL Server is not ready to accept new client connections. Wait a few minutes before trying again. If you have access to the error log, look for the informational message that indicates that SQL Server is ready before trying to connect again.

    We are on SQL Server 2014 SP1, I am checking online to see if I can get any useful information for troubleshooting.

    Any help would be greatly appreciated.

    Thanks!

  • Do you have any other error messages in the log? This is a generic message which comes when SQL is starting and is not ready to accept connections.

    Please check the SQL Error log and there should be some more relevant error messages.

  • It just means that someone was trying to connect while SQL was still starting up. It's not an error.

  • This is not an error. You must dig for the causes that leaded to the SQL Server restart on the previous errorlog and in the eventviewer.

    If the database instance is in cluster, check also the events in the cluster administrator.

  • Thanks much for looking into this, I also found few other errors from SQLLog (preciously from SQLDump0001.mdmp).

    Though I couldn't quite follow this error message, please let me know if that helps.

    Thanks again for looking into this.

  • I am also getting similar error from crash dump and SQL is restarting after very 30 minutes
