Hi,
My kernels are running:
3.8.11-200.fc18.x86_64 and 3.8.9-200.fc18.x86_64
My cephx settings are below
auth cluster required = cephx
auth service required = cephx
auth client required = cephx
I will be working on my test cluster later this week and will try to reproduce
and will file a bug then.
Joe

What kernel version? Are you using cephx authentication? If you could
open a bug at tracker.ceph.com that would be most helpful!

Not currently. You can do this yourself with 'timeout 120 ...' with any
recent coreutils.
