Description of problem:
Red Hat customer came across a series of kernel panics with the following panic string:
"kernel BUG at lib/idr.c:1157!"
on systems hosting docker with Mesosphere Kubernetes clustering. Systems are all in the same cluster and had active docker containers running. The panics are all due to kmemcg_id value being -1 (0xffffffff) everytime. Customer indicates after adding swap space, the issue no longer occurs.
Version-Release number of selected component (if applicable):
Unknown. Customer is unsure if it is reproducible
Steps to Reproduce:
