Sam Tunnicliffe updated CASSANDRA-16316: ---------------------------------------- Bug Category: Parent values: Degradation(12984)Level 1 values: Resource Management(12995) Complexity: Normal Discovered By: User Report Fix Version/s: 3.11.x 3.0.x 2.2.x Severity: Normal Status: Open (was: Triage Needed) Thanks for the report [~Jan Karlsson], I believe you're right. It seems like overriding {{afterExecute}} in the {{AuthCache}}'s executor and not calling {{maybeResetTraceSessionWrapper}} is the cause. I had a quick check but I wasn't able to repro on trunk, the way that the background refreshes are done changed a bit with CASSANDRA-14497, which may have helped. That said, I didn't spend too long trying to repro, so I could have just missed something. > Tracing continues after session completed > ----------------------------------------- > > Key: CASSANDRA-16316 > URL: https://issues.apache.org/jira/browse/CASSANDRA-16316 > Project: Cassandra > Issue Type: Bug > Components: Observability/Tracing > Reporter: Jan Karlsson > Assignee: Jan Karlsson > Priority: Normal > Fix For: 2.2.x, 3.0.x, 3.11.x > > > We saw the system_trace.events table increasing in size continuously without > any trace requests being issued. > I traced the issue back to a specific version and patch. I believe we have > removed the call to reset the trace flag in CASSANDRA-15041 which causes > tracing to continue in the thread even after it is finished with the request. > Reproduced like follows: > 1. ccm test -n 1 -v 3.11.9 > 2. Enable authentication/authorization > 3. Set permissions_update_interval_in_ms: 1000 (It works if this value is > default value. I am guessing this is because the update is done in the > calling thread) > 4. select * from some table a bunch of times until PermissionRoleCache is > refreshed > 5. Watch system_traces.events grow > -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
