Hi, thanks for the help!
I've changed the deviceid's for all the LM's in the building, and none of them have the same id and I'm certain no other BACnet device use these ID's either.
This LM in particular has around 2000 BACnet objects.
It doesnt just happen on this LM, it happens on most of them. Is there anything else I could do to diagnose this issue? The system load is for the most part < 1, but it does of course spike at times.
I use AVEVA Plant SCADA as the BACnet client to these LM's and there is quirk in the BACnet driver there that causes all the objects that get a negative ack like `unknown-object` to get dropped from polling and revert to #BAD, without ever recovering on their own.
