I monitor the online status of this node server with a program and the node server briefly goes offline a few times a day.  Here are a couple of errors I say in the log that coincides with the offline.

Any idea what's causing these parsing errors?

Thank you in advance. 

when the node server queries the Ambient server for data, what it gets back is not valid data.  The node server then marks the station as offline until a query responses with valid data.

Okay thanks Bob.
