I register the Appian as a windows service. It always fails to start part of the engines. I use command line &quot;start-suit.bat&quot; now. It works well.<div style="clear:both;"></div>RE: Exception occurred like below when starting Jboss server.

You may want to look at the engine and database logs (gw_PX021... and db_PX021...) at the time the engine disconnected and confirm if there ware any error messages that may indicate why the engines keep restarting.<br />Ensure there is enough memory and disk space to start the engines.<div style="clear:both;"></div>RE: Exception occurred like below when starting Jboss server.
