Brandon Williams commented on CASSANDRA-16316:
----------------------------------------------
Could you add a test that show it solves this behavior?
> 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
