Network UPS Tools (NUT) error, data stale

I have a server that monitors my network. It has two APC UPSes connected to it via USB. If I connect one or the other NUT works fine and gives all the information flawlessly, however, as soon as I connect both of them NUT will only give information about one of them. The other just says the data is stale. Here is the output from /var/log/messages

Data for UPS [secondups] is stale - check driver

I could move one UPS to one machine, and keep one here, but the idea is one machine does all the monitoring and keeps the others as clients.

That being said, any ideas to resolve this would be great.

Thanks

I've never used NUT so I am unfamiliar with the details but make sure your ups.conf file contains all the specific information for both units. If they are the same make/model then you probably need to add a serial number to differentiate between the two units.
