Will Hayworth commented on CASSANDRA-11172:
-------------------------------------------
debug.log? I can go hunt through my compressed files but this quickly pushes
the other logs out of rotation. I've watched it happen. Thousands upon
thousands of lines. And it's happened for a bunch of different nodes. The
solution has been to kill them and restart but it's temporary.
I just checked--all 20 zipped system.logs are filled with 40,000+ lines like
the ones in my sample file. I was going to upload some to you but they're just
identical, including the earliest lines I have:

> 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
> Attachments: beep.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.
