I have configured NodeLink to use with a Honeywell Alarm Panel.

 

Yesterday, I noticed that the application was generating large volume of the following (error) messages.

Any suggestions on how to address this?

Appears to be the EVL closing the connection.  That's the error I typically see when there are multiple device (or instances of a program) trying to connect to the EVL at the same time.

I was seeing the same, rebooted the EVL and all is fine now.
