Description of problem: Atomicity of messages sent under XA is lost when qpidd is killed and started again. A message that is read under an XA transaction is redelivered on reconnect. Version-Release number of selected component (if applicable): qpid-jca-0.18-8.el6.noarch qpid-jca-xarecovery-0.18-8.el6.noarch How reproducible: 100 % Steps to Reproduce: 1. send a number of messages to a queue in one xa transaction 2. read messages from queue with MDB one by one using xa , store messages to a DB 3. kill qpidd and start qpidd 4. read the rest of messages with MDB, storing them to the DB 5. check the number of messages in the DB Actual results: In the DB, there is a large number of duplicate messages found (1 to 25 % of the original number) Expected results: In the DB, only messages that were found in the queue should be found, with no duplicates. Additional info: Additionally, the test was run without the database (to avoid possible DB malfunctioning). Instead an auxiliary queue was used to store read messages. The result is exactly the same.
