We've now added libcgroup to the errata and a new puddle has been built. Please see if the issue still exists.
Re-test this bug with OpenShiftEnterpriseErrata/2.2/2017-01-25.4, and FAIL.
The version of libcgroup added into errata is the same version as the initial report (0.40.rc1-23.el6). So this bug still reproduced.
I've talked with a libcgroup engineer and they think they've found the problem and gave us a scratch brew build. I've edited the latest puddle to use this libcgroup instead.
Please check that libcgroup 0.40.rc1-24 is being used and see if the problem still exists. If this fixes the issue, I'll go back to the libcgroup folks and libcgroup can be updated.
Verified this bug with libcgroup 0.40.rc1-24 build in OpenShiftEnterpriseErrata/2.2/2017-01-25.4 puddle, and PASS.
No ssh issue is seen now.
