After upgrading to 2.1.7, OpsCenter (see pic here: https://dl.dropboxusercontent.com/u/255268/compactions_public.png) is showing a really high number of Total Compactions (no change in the overall load and in the actual number of compactions pending). Could this issue be related?

> There's more race conditions affecting compaction task submission than CASSANDRA-7745, so to prevent some of these problems stalling compactions, I propose simply submitting background compactions once every minute, if possible. This will typically be a no-op, but there's no harm in that, since it's very cheap to do.
