Posted this to the forums with no response... I'm getting this problem with JBoss 3.0.4 and I'm wondering if anyone has experienced something similar. I have multiple applications connecting to the same database using a shared data source service. If the applications are being used simultaneously, at some point the ManagedConnectionFactory becomes null for one of the applications. I've worked around this for now by using separate data source services per application and will probably upgrade to JBoss 3.2.x later on... but I'm interested if someone can confirm that this was an issue with JBoss 3.0.4 or whether I need to investigate further.
