[jira] Created: (QPID-1936) Potential for deadlock when using
durable ring queues
Potential for deadlock when using durable ring queues
-----------------------------------------------------
Key: QPID-1936
URL: https://issues.apache.org/jira/browse/QPID-1936
Project: Qpid
Issue Type: Bug
Components: C++ Broker
Affects Versions: 0.5
Reporter: Gordon Sim
Assignee: Gordon Sim
Fix For: 0.6
When a message is evicted from a durable ring queue (due to arrival of a new message when queue is at its limit), the dequeue request to the store plugin (if loaded) is done with the Queues messageLock held. Depending on the store plugins locking, this causes the potential for deadlocks and shouldbe fixed so that no lock is held when calling dequeue() (as is usually the case).
