[JENKINS-66441] Build Loop from SCM not Updating

I'm not sure if this is the right plugin, but we've been building what's known as the MOOSE framework for several years with Jenkins without much fuss. Today, I noticed that Jenkins built the same commit like 17 times once per hour (H * * * *) yesterday with Jenkins claiming there was an SCM change, and all of the polling logs look like what's below. The last time I updated the Jenkins version and plugins was also just over a week ago. For whatever reason, it stopped misbehaving on its own, but I'd like to understand what happened here to avoid future build spam.
