Can you try putting in a pause after initializing the local device, using "Thread.sleep(###)"? There may be a delay while the device waits to join the network, during which your requests might be timing out. Start with something like 10 seconds to see if this works, and then reduce the time as much as you can.

Hi Nik,

I've personally had some issues with Ubuntu, but i'm far from being able to say for sure that's the problem. Still, i suggest trying Fedora or a Windows host for Mango to see if your serial ports stick around longer.

Also, make sure data sources and testers aren't competing for the port in the case that you have multiple data sources running. Only one running data source can own a serial port at a time. Note also that the node scanner owns the port while it is scanning.

Yes, you can do what you like with the sources within the constraints of the GPL license. The license for seroUtils is not defined, but it is intended to be used only as support for Mango. I would be inclined to grant its use as support for Mango derivatives under GPL as well.

Yeah, still not the information i was hoping for. Do you use COV in your points? Also, what kind of event is raised: a device exception, or a message exception? Sorry for all the questions, but it would be great to track this down. Could you provide a chuck of the events so that i can check the timestamps for any clues?

Yeah, that's the latest version. Can you check the logs to see if there are any stack traces associated with that error message? It indicates a condition where the code is doing something it shouldn't, and it should be fixed.

Hi Iain,

What version of the BACnet module are you using? I recall that there were some recent changes (i.e. a couple months ago) that addressed an error message like this.

Mebius,

Do you have a single data source that is getting points from the BACnet device, or do you have multiple? If the latter, you might have multiple simultaneous requests going to the device, which it may not be able to handle, causing timeouts and the appearance of a slowdown.

I know at least that even the BACnet MS/TP is capable of polling for thousands of points without problems, subject to the speed of the connection. (I know you are using I/P, which should be much faster than MS/TP.)

The line is not in the CVS code. Perhaps it still is in the src jar file. Try using the repo source instead.

Check out maintenance events.
