SQL Error: 0, SQLState: 08S01 Communications link failure

Question

I am getting this error (not so frequently):

2013-05-08 16:44:35,786  WARN (JDBCExceptionReporter.java:100) [org.hibernate.util.JDBCExceptionReporter, logExc         


        

Answer 1

The communication link between the driver and the data source to which the driver was attempting to connect failed before the function completed processing. So usually its a network error. This could be caused by packet drops or badly configured Firewall/Switch.
