Michael McCandless commented on LUCENE-4510:
--------------------------------------------
Thanks [~dweiss], [~rcmuir] and [~uschindler]! I will attempt all of the above
solutions when I next need it again :)
> when a test's heart beats it should also throw up (dump stack of all threads)

> Key: LUCENE-4510
> URL: https://issues.apache.org/jira/browse/LUCENE-4510
> Project: Lucene - Core
> Issue Type: Bug
> Reporter: Michael McCandless
> Assignee: Dawid Weiss
> Priority: Major
>
> We've had numerous cases where tests were hung but the "operator" of that
> particular Jenkins instance struggles to properly get a stack dump for all
> threads and eg accidentally kills the process instead (rather awful that the
> same powerful tool "kill" can be used to get stack traces and to destroy the
> process...).
> Is there some way the test infra could do this for us, eg when it prints the
> HEARTBEAT message?
