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.
