Cluster node restart fails when producers and consumers are attached to the
same queue on a same client.
--------------------------------------------------------------------------------------------------------
Key: QPID-3495
URL: https://issues.apache.org/jira/browse/QPID-3495
Project: Qpid
Issue Type: Bug
Components: C++ Broker, C++ Clustering, Java Client
Affects Versions: 0.12
Environment: * RHEL release 5.5 (Tikanga) x64
* OpenAIS 0.80.6-16.el5
* Fails on both: qpid-cpp-0.12(apache) and qpid-cpp-0.10(mrg)
Reporter: Jaakko Nyman
Attachments: qpid-cluster-problem.tar.gz
Description of the problem:
1) start a cluster on two nodes N1 and N2
2) start process p1 with consumer C1 and producer P1 for queue Q. C1 uses JMS
Target T1
3) start process p2 with consumer C2 and producer P2 for queue Q and sending
one text message / sec to queue Q with target T1. C2 uses JMS Target T2.
4) confirm with tcpdump that N1 is retrieving the traffic
5) shut down node N1 with 'qpidd --quit'
6) wait for 5 sec
7) restart node N1 with 'qpidd'
8) check the qpidd.log with the error catch-up connection closed prematurely
Test code is attached with this bug report, the case is actually simpler than
it seems from the previous description and reading the test code should clarify
the problem.
Configuration files:
qpidd.conf:
cluster-mechanism=ANONYMOUS
cluster-name=MYCLUSTER
log-to-file=/home/qpid/qpid.log
daemon=yes
no-data-dir=yes
auth=no
openais.conf:
totem {
version: 2
secauth: off
threads: 0
interface {
ringnumber: 0
bindnetaddr: 172.16.133.0
mcastaddr: 226.94.1.1
mcastport: 5405
}
}
logging {
debug: off
timestamp: on
}
amf {
mode: disabled
}
Steps for running the test repeating the problem:
1) Download, extract and compile attachment qpid-cluster-problem.tar.gz
2) Start two QPid nodes on a cluster
3) Start ConsumerTest.class and ProducerTest.class on a third node
4) Restart nodes as described previously
5) Change attribute ProducerTest.TEST_SCENARIO=2 on the source code and test
again. The cluster node restarts should work because producer and consumer are
now attached to separate queues on both ConsumerTest and ProducerTest.
