> Zombie Stomping Session
> -----------------------

> Key: HBASE-14420
> URL: https://issues.apache.org/jira/browse/HBASE-14420
> Project: HBase
> Issue Type: Umbrella
> Components: test

> Priority: Critical
> Attachments: hangers.txt, none_fix.txt

>
> Patch build are now failing most of the time because we are dropping zombies.
> I confirm we are doing this on non-apache build boxes too.
> Left-over zombies consume resources on build boxes (OOME cannot create native
> threads). Having to do multiple test runs in the hope that we can get a
> non-zombie-making build or making (arbitrary) rulings that the zombies are
> 'not related' is a productivity sink. And so on...
> This is an umbrella issue for a zombie stomping session that started earlier
> this week. Will hang sub-issues of this one. Am running builds back-to-back
> on little cluster to turn out the monsters.
