Control-C
qmf-agent crashes occasionally on Control-C
-------------------------------------------
Key: QPID-2132
URL: https://issues.apache.org/jira/browse/QPID-2132
Project: Qpid
Issue Type: Bug
Components: C++ Broker
Reporter: Ken Giusti
Reproducible on trunk.
Run the qmf-agent (cpp/examples), hit control-C to interrupt it - segfaults about 1 or 2 times out of ten.
Race condition on cleanup of ManagementAgentImpl class. I'll post a patch shortly....

Ken Giusti reopened QPID-2132:
------------------------------
Additional issue - the fix works, but only for the connection management thread (connThread). Same issue exists for publish thread (pubThread). Less likely to hit due to the longer timeouts, but I can occasionally hit it now that the connThread fix is in place.
Core was generated by `./qmf-agent 127.0.0.1 59736'.
