[jira] Created: (QPID-1261) Deadlock when using rdma
Deadlock when using rdma
------------------------
Key: QPID-1261
URL: https://issues.apache.org/jira/browse/QPID-1261
Project: Qpid
Issue Type: Bug
Components: C++ Broker
Affects Versions: M3
Reporter: Gordon Sim
Assignee: Gordon Sim
Fix For: M4
The upcoming rdma transport uses a slightly different threading model and can deadlock due to the message lock being held across notify calls on consumers in qpid/broker/Queue.cpp (lock ordering issues with SessionState::lock).
