Perf page display fails with error

[zenoss]

Perf page started failing a couple of nights ago, Monday 8/18, I think. Not sure if it's relevant but I had added datapoints for Ping RTA and Loss first at the device level, then went back and added them on the Ethernet template for the Interface level. The device level performance page including the graphs was displaying fine before I added the interface level ones. Both device and interface level graphs displayed OK after I added the interface level. And then boom, the error below occurred. Removing the datapoints did not resolve the issue.

This error is caused by binding the ethernetCsmacd template directly to the device. You should not do this because Zenoss automatically binds this template once-per-interface for every interface on the device.

See the following explanation of template binding:
