    Any ideas what that might be? Array index is interesting. The solution is just to restart the data source.

    Just to add, all of the devices started talking to their Bacnet slaves as soon as the data source was restarted. I would really like to get to a point where this could recover on its own.

    @psysak I'll be working in the BACnet4J library later this week or early next. This looks like a potential bug so I'll see if I can fix it up for you while I'm in there.

    @psysak It looks like you are using an older version of the BACnet4J library, I would suggest using the latest version 4.1.6 and see if you still have the problem. If you do then re-post the new stack trace so I can see how it fits in the latest code. I'm working on the library this week so if you can get the me the info before I move on then I'll make a fix if something is broken.
