Description

This issue was created by maloo for Bob Glossman <[e-mail]>

This issue relates to the following test suite run: http://maloo.whamcloud.com/test_sets/8a4b07d8-724d-11e3-a03d-52540035b04c.

All subtests passed, but the test suite failed. console logs of all nodes show disconnect/reconnect after the end of the SKIPped test_15 at about the same time according to timestamps. ConMan failures are followed by what looks like kernel reboot console output in all node console logs. example:

This doesn't look like a single node crash or failure as similar content in console logs from all the VMs.
