Emanuel Muckenhuber <emuckenh at redhat.com> made a comment on [bug 1006246|https://bugzilla.redhat.com/show_bug.cgi?id=1006246]

Description of problem:

Executing a reload operation using the native mgmt API sometimes results in a channel closed error. Upstream already has some better handling for handling this which should be ported back to EAP6.
