Since this could be a runtime regression I'd like this triaged and investigated. I assume it could be just a poorly handled error but that's no excuse.

@Kargakis @jwhonce @bparees @mfojtik @ewolinetz @simo5 @pweil- @tnozicka @sjenning I have a suspicion that #16994, #16881, #16985, #16023 and this issue are all duplicates of each-other. If you think so, I suggest closing the others and renaming this issue process_linux.go:258: applying cgroup configuration for process caused \"open /sys/fs/cgroup/pids/kubepods.slice/kubepods-besteffort.slice/.../cgroup.procs: no such file or directory.
