Subject [jira] [Updated] (CASSANDRA-15846) BusyPoolException with OperationTimedOutException
Date Tue, 30 Jun 2020 09:43:00 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-15846?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sylvain Lebresne updated CASSANDRA-15846:
-----------------------------------------
    Resolution: Not A Problem
        Status: Resolved  (was: Triage Needed)

I'll close because as said above, I really don't think this is any indication of a server
bug or issue. But if you have more information that suggests otherwise, please feel free to
re-open with that additional information.
