[jira] [Commented] (BOOKKEEPER-67) BookieReadWriteTest gets blocked
and never finishes
[ https://issues.apache.org/jira/browse/BOOKKEEPER-67?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13104365#comment-13104365 ]
Flavio Junqueira commented on BOOKKEEPER-67:
--------------------------------------------
Matthieu, Does it get stuck on every run? I'm not sure what you mean with "systematically".
I have just run a couple of times and confirmed that it works for me. Is there anything special about your environment? Also, just to confirm, are you waiting long enough? There are 24 tests to run in ReadWrite test set.

> I systematically reproduce this behaviour on the linux boxes I tested with.
> The test gets stuck acquiring permits from a semaphore, normally used for throttling:

> The issue might come from the synchronization mechanism used in the test itself.
