             Summary: HA broker deadlocks under load with transactions
                 Key: QPID-5145
                 URL: https://issues.apache.org/jira/browse/QPID-5145
             Project: Qpid
          Issue Type: Bug
          Components: C++ Clustering
    Affects Versions: 0.25
            Reporter: Alan Conway
            Assignee: Alan Conway


HA broker deadlocks when subjected to load involving local transactions.

To reproduce: start a 2 node cluster and run this:

qpid-cpp-benchmark --repeat 10 -b 20.0.20.200 --summarize -q 6 -s 3 -r 3 -m 10000 --connection-options {tcp-nodelay:false,reconnect:true,heartbeat:1} --send-arg=--tx --send-arg=10 --receive-arg=--tx --receive-arg=10

Expected result: benchmark should completes normall
Actual result: Primary broker deadlocks with stack trace showing many threads blocked in __lll_lock_wait.
