Steven Hawkins commented on TEIID-5054:
---------------------------------------

[~asmigala] Set autoFailover=true and issue a query that has multiple result batches.  Fully read the results.  You can also use the unit test https://github.com/teiid/teiid/blob/01b968a220e981ee820ab1b07df148833eb8b995/runtime/src/test/java/org/teiid/transport/TestCommSockets.java#L356 without the fix it will hang.

> With autoFailover=true there is a periodic ping before usage of the connection.  This ping may be called during processing of multi-batch results such that the ping call effectively hangs.  4 minutes later (or whatever the synch timeout is) the client will attempt to failover.
