Jiri Daněk commented on PROTON-2225:
------------------------------------
Furthermore, I've seen it sometimes freeze on older clang (flaky on xenial
https://travis-ci.com/github/jiridanek/qpid-proton/jobs/337482058#L2049,
freezes reliably on xcode
https://travis-ci.com/github/jiridanek/qpid-proton/jobs/337466798#L2165) and
flaky leak on gcc xenial,
https://travis-ci.com/github/jiridanek/qpid-proton/jobs/337466791#L1779.

> Project: Qpid Proton
> Issue Type: Test
> Components: build
> Affects Versions: proton-c-0.31.0
> Reporter: Jiri Daněk
> Assignee: Jiri Daněk
> Priority: Major
>
> Previously, the test stopped compiling, as fixed in PROTON-2120. The reason
> the test is disable is that the test is failing when it is run.
> Instead of disabling the test, it would be better to have the test running,
> suppress the reported errors and fill a jira to get them fixed eventually.
> This requires writing suppressions for both helgrind and tsan.
> Now that fd-limit test is disabled (PROTON-2172), we should have some other
> test to highlight issues from PROTON-2133.
> Current state is that threaderciser test builds and fails with
> {noformat}
> threaderciser start: threads=8, time=1, actions=[listen, close-listen,
> connect, close-connect, wake, timeout, cancel-timeout]
