[~msb] what happens if you restart a node?

could you enable debug logs on one node?

You would need to edit conf/logback.xml on one node, add this before the end tag somewhere:
{{<logger name="org.apache.cassandra.db.compaction.LeveledManifest" level="DEBUG"/>}}

and grep the log for "Estimating" when you do a nodetool compactionstats

> pending tasks: -222222228
> I can see negative numbers in 'pending tasks' on all 8 nodes
