--------------------------------------------------------------------------------------
Key: QPID-2523
URL: https://issues.apache.org/jira/browse/QPID-2523
Project: Qpid
Issue Type: Bug
Components: C++ Broker
Affects Versions: 0.5, M4, 0.6
Reporter: Rajith Attapattu
Assignee: Rajith Attapattu
Fix For: 0.7
Description of problem:
When reloading a large acl file , the broker core dumps.
This surfaced while running the attached reproducer.
How reproducible:
Always - reproducer attached.
Steps to Reproduce:
1. Start the broker with the acl module and and --acl-file /tmp/policy.acl
2. The initial acl file should contain only "acl allow all all"
3. run the message_sender.py (This program will keep on publishing to
amq.direct)
4. run acl_reloader.py with --mode allow | deny a few times
Actual results:
The broker core dumps.
Expected results:
The broker should continue to work after reloading the acl file properly.
Additional info:
Following is the backtrace from the code dump.
