Hi,

A Jenkins job running on Openshift generated a PermGen expcetion.  I ran
the job a couple more times to see if it would pass. I then realised that
my two nodes had completely crashed. (i.e. I can't even login to the hosts,
they have to be forcibly rebooted).

Leaving aside the reason for the PermGen error, it's worrying that an
exception inside a container could kill the entire node like that. And
then, as the container is re-deployed to another node, it kills that one
too. The entire cluster can be brought down by a naughty Jenkins job.

How do I protect my cluster against this?

Thanks

Lionel.
