Unless there is a reason for it, you should not write error handling for any specific errors. It is even impossible to enumerate all possible errors that can occur, so such task would be hopeless.

This error should be issued in relation to communication problems or a recovery from them. As with other errors, the communication should reestablish when it becomes possible. No reason to handle this error (specifically if the recovery works).
