[jira] [Closed] (QPID-3972) Cluster crash when configured as a
federation source with qpid-route "--src-local'
[ https://issues.apache.org/jira/browse/QPID-3972?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Alan Conway closed QPID-3972.
-----------------------------
Resolution: Won't Fix
Old cluster module no longer supported.
> 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:
