I would love to know how to properly troubleshoot them and shut them up. One of the Chassis has been complaining about Env stats for a while but performing services fine. Now another is griping about the same thing. All of the fans appear to be spinning and while the co-loc room that houses these is warmer than I would like, they are still well within normal operating temperatures. Any suggestions for these errors coming through my Total Controls? I have a spare ready to throw in production if need be, but all services are performing normally at the moment. I'm pretty comfortable with the TCs we have, but I know they can be finicky. Let me know if there is more information that would help others help me troubleshoot this. Thanks for help and suggestions in advance. Gerald
