> Key: CASSANDRA-17205
> URL: https://issues.apache.org/jira/browse/CASSANDRA-17205
> Project: Cassandra
> Issue Type: Bug
> Components: Local/SSTable
> Reporter: Josh McKenzie
> Assignee: Josh McKenzie
> Priority: Normal
>
> LogTransaction.SSTableTidier holds a reference to a {{Tracker}} which holds
> references to both a {{ColumnFamilyStore}} and a {{View}}, both of which hold
> refs to SSTableReaders. As per the comment at the top of the SSTableTidier:
> {quote}// must not retain a reference to the SSTableReader, else leak
> detection cannot kick in
> {quote}
> We shouldn't hold a reference to the Tracker here; long running unit tests
> w/-Dcassandra.debugrefcount=true had this pop up.
> {code}ERROR [Strong-Reference-Leak-Detector:1] 2020-10-27T01:10:12,421
> NoSpamLogger.java:97 - Strong self-ref loop detected{code}
