[jira] [Commented] (CASSANDRA-14451) Infinity ms Commit Log Sync
[ https://issues.apache.org/jira/browse/CASSANDRA-14451?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16497916#comment-16497916 ]
Jason Brown commented on CASSANDRA-14451:
-----------------------------------------
As I suspected, this is just a bug with logging (due to CASSANDRA-14108), and no real behavior or correctness is impacted. I have a patch for 3.11, but need to port to 3.0 and trunk.
