Subject [jira] [Commented] (LUCENE-4510) when a test's heart beats it should also throw up (dump stack of all threads)
Date Sat, 27 Oct 2012 20:29:12 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-4510?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13485494#comment-13485494

Robert Muir commented on LUCENE-4510:
-------------------------------------

Actually getting to the step of printing the PID in the heartbeat message would be really
useful!

> 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?
