             Summary: dtest: log-watching thread leak and thread starvation
                 Key: CASSANDRA-14558
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-14558
             Project: Cassandra
          Issue Type: Bug
          Components: Testing
            Reporter: Stefan Podkowinski
            Assignee: Stefan Podkowinski


We get occasional build timeouts on b.a.o after pytest becomes unresponsive for over 20 minutes. This will result in a thread dump like this one:

[https://builds.apache.org/view/A-D/view/Cassandra/job/Cassandra-2.2-dtest/117/consoleFull]

If you look for "Log-watching thread starting" messages and the dump, it becomes quite obvious whats the issue here.

I had a quick look at the python3 / pytest related changes in CASSANDRA-14134 and it seems that some of the handling around dtest_setup's {{log_watch_thread}} var has been changed in a way that would prevent eventually yielding the allocated thread.
