Hi, I am not sure about this one. It happened to me in the past as well. I never really wondered about it as it was gone after a while or a restart off the top of my head. To get rid of it, a restart might be enough.
But if you feel like troubleshooting this, I think the first thing is to try to see if compactions are really happening. Maybe using JMX, I believe `org.apache.cassandra.metrics:type=Compaction,name=PendingTasks` is what is used by 'nodetool compactionstats' but they might be more info there. Actually I don't really know what the 'system.compactions_in_progress' was replaced by, but any way to double check you could think of would probably help understanding better what's happening. Does someone now the way to check pending compactions details in 3.0.9?
