Unable to start the DSCManager

We recently ran into a situation where we would see the following error when trying to start an ES2.5 instance of LiveCycle:

Upon further investigation, the transaction timeout simply wasn't long enough and this process was timing out, which caused many other issues with the server.  We then found http://helpx.adobe.com/livecycle/kb/unable-start-dscmanager.html and changed the TransactionTimeout in conf/jboss-service.xml to 600.
