I noticed a lot of slaves were down, and was pointed to this by a few
people - on chat.openshift.io and irc.freenode : on investigation it
looked like jenkins master had exhausted ram and other jobs on the
machine were killing the cpu with loads upto 50.x; I had to restart the
jenkins master to bring services back.

once Brian is online, he will likely do a more through investigation and
get back with details.
