Ganesh Murthy created DISPATCH-1272:
---------------------------------------
Summary: Router crashes when detach from reciver and detach from
broker arrive at the same time on a link route
Key: DISPATCH-1272
URL: https://issues.apache.org/jira/browse/DISPATCH-1272
Project: Qpid Dispatch
Issue Type: Bug
Components: Container
Affects Versions: 1.5.0
Reporter: Ganesh Murthy
Assignee: Ganesh Murthy
Fix For: 1.6.0
A receiver attaches to the router on a link routed address which is serviced by
the router via a route-container connection connected to the broker.
When the receiver and the broker send detaches at the same time, the receiver
side pn_link gets freed and the router tries to forward the detach received
from the broker on to this freed pn_link and crashes.
