[jira] [Created] (QPID-3972) Cluster crash when configured as a
federation source with qpid-route "--src-local'
Ken Giusti created QPID-3972:
--------------------------------
Summary: Cluster crash when configured as a federation source with qpid-route "--src-local'
Key: QPID-3972
URL: https://issues.apache.org/jira/browse/QPID-3972
Project: Qpid
Issue Type: Bug
Components: C++ Broker, C++ Clustering
Affects Versions: 0.17
Reporter: Ken Giusti
Assignee: Alan Conway
When configuring a cluster as a source of a federation route, and making the route a "push" route, will cause all the cluster members to crash.
To reproduce:
Start a stand alone broker, and a cluster of brokers (two in this example):
./qpidd --auth no -p 6001
./qpidd --auth no --no-data-dir --load-module .libs/cluster.so --cluster-name ken -p 7001
./qpidd --auth no --no-data-dir --load-module .libs/cluster.so --cluster-name ken -p 7002
Configure a simple queue route from the cluster to the standalone broker, using the --src-local option to make the route a "push" route:
[kgiusti@localhost src]$ source ./tests/test_env.sh
[kgiusti@localhost src]$ qpid-config --broker=127.0.0.1:7001 add queue srcQ; qpid-config --broker=127.0.0.1:6001 add exchange fanout destEx; qpid-config --broker=127.0.0.1:6001 add queue destQ; qpid-config --broker=127.0.0.1:6001 bind destEx destQ
[kgiusti@localhost src]$ qpid-route --src-local queue add 127.0.0.1:6001 127.0.0.1:7001 destEx srcQ
Failed: Exception - exception received from messaging layer: (None, 'connection aborted')
Both clustered brokers crash on executing the qpid-route command. The 127.0.0.1:7001 broker appears to crash due to an inconsistency when subscribing to the route:
