Relay suddenly begins refreshing commands way too fast

[nmohoric]

Currently my relay is set to refresh commands every 30 seconds, at some point it starts updating every 1-2 seconds which is much too fast and causes some high load.

This feels like a problem with the timer but seems simple enough that I'd be surprised if that were the case....
