Marcus Eriksson commented on CASSANDRA-11172:
---------------------------------------------
Think I found the issue, this happens if you do nodetool repair -full (when
replacing repaired sstables there was an assumption that the sstables was
unrepaired before, but that is not the case when you do -full repairs)

> Infinite loop bug adding high-level SSTableReader in compaction
> ---------------------------------------------------------------
>
> Key: CASSANDRA-11172
> URL: https://issues.apache.org/jira/browse/CASSANDRA-11172
> Project: Cassandra
> Issue Type: Bug
> Components: Compaction
> Environment: DSE 4.x / Cassandra 2.1.11.969
> Reporter: Jeff Ferland
> Assignee: Marcus Eriksson
> Fix For: 2.2.x, 3.0.x, 3.x
>
> Attachments: beep.txt, tpstats_compaction.txt,
> trapped_in_compaction.txt, trapped_in_compaction_mixed.txt
>
>
> Observed that after a large repair on LCS that sometimes the system will
> enter an infinite loop with vast amounts of logs lines recording, "Adding
> high-level (L${LEVEL}) SSTableReader(path='${TABLE}') to candidates"
> This results in an outage of the node and eventual crashing. The log spam
> quickly rotates out possibly useful earlier debugging.
