>
> After upgrading from cassandra 2.0.x to 2.1.10, we began seeing problems
> where some nodes break the 12G commit log max we configured and go as high as
> 65G or more. Once it reaches this state, "nodetool compactionstats" hangs. I
> watched the recovery live when compactions begin happening again. the
> "nodetool compactionstats" suddenly completed to show the outstanding jobs
> most in 100% completion state:
> {code}
