Description James Livingston 2014-09-11 23:03:36 UTC 
If a CLI session is open and there is a long OS-level pause, such as from the hypervisor snapshotting a guest VM, it can cause a race between the shudown and read processing.

This was fixed in https://github.com/xnio/xnio/commit/2bdbbf2d2

Comment 2 Hynek Mlnarik 2014-10-13 07:56:15 UTC 
FailedQA in 6.4.0.DR4. I was unable to reproduce the XNIO-237 stacktrace with DR4, yet there is another - repeatable - deadlock which is also found in the customer case, described in bug 1151960.

Comment 5 Hynek Mlnarik 2014-11-25 15:36:40 UTC 
Verified in EAP 6.4.0.DR11. No deadlock found in the critical areas of CLI.
