> While upgrading the cluster from 2.1.16 from 3.11.2, after a few hours most
> of the upgraded nodes started to go in a compaction infinite loop and showing
> many events like the one below (always for the same SSTable):
> {code:java}
> INFO [CompactionExecutor:4] 2017-10-29 00:28:31,480 LeveledManifest.java:474
> - Adding high-level (L5)

> to candidates
> {code}
> Since the log get spammed at a huge rate, I'm unable to get any previous
> events.
> Tried restarts and sstablescrub -m without success. The only workaround that
> seems to work (so far) was sstablelevelreset.
> I've attached the dump.
