java.net.SocketException: Broken pipe

Question

I am getting this for all the database connections from my app server..
This exception occured for couple of hours, then got fixed by itself.
Something to do with network connection from the appserver?

Answer 1

For MySQL, "By default, the server closes the connection after eight hours if nothing has happened." And, MySQL has a reconnect feature that supports auto-reconnect after the closed connection is detected on the client side.

Eight hours? With the use of connection pooling or a long-running background job, that is possible.

Answer 2

During a write the connection was severed, this can be due the the destination closing the connection or the destination process has terminated. Its not an error with your implementation.

It means you client has disconnected from the server; check if it is running. See here
