Resource Allocation Issue in Weblogic messaging bridges

Question

Hi,
We are using
Weblogic version à WebLogic Server 8.1 SP5 Mon Sep 19 23:06:54 PDT 2005 641358 WebLogic XMLX Module 8.1 SP5 Mon Sep 19 23:06:54 PDT 2005 641358 WebLogic Temporary Patch for CR250915 04/18/2006 22:21:33
Java JDK version à 1.4.2_11
Oracle version à 9.2.08
Solaris version à Solaris 5.8
The weblogic application is deployed on Unix Solaris.
We have configured 8 message bridges within weblogic between the 8 Topics in weblogic (source JMS destination) and 8 topics in the External EMS server (Target JMS destination) .
The properties set for the message bridges are
1] AsyncEnabled ="true"
2] DurabilityEnabled ="true"
3] QualityOfService="Exactly-once"TransactionTimeout="10"
4] TransactionTimeout="10"
The source and target JMS destinations are bridge using the resource adapter of jms-xa-adp (connector module)
The properties for the Source JMS Destination are
1] ConnectionFactory = weblogic.jms.client.JMSXAConnectionFactory
The properties for the Target JMS Destination are
1] InitialContextFactory = com.tibco.tibjms.naming.TibjmsInitialContextFactory
2] ConnectionFactory = XATopicConnectionFactory
The EMS client version library is EMS version client library à 4.2.0
The message Bridge Thread Pool Size is à 12
When the weblogic is started, all the bridges comes up properly and are forwarding message to the target, however after some time (1 to 2 days) we observe some that some of the bridges are going down and we get see following error in the weblogic logs
####<May 26, 2010 12:00:56 AM GMT> <Warning> <Connector> <ngun015> <zlw1rdbs12-a> <ExecuteThread: '6' for queue: 'MessagingBridge'> <<WLS Kernel>> <> <BEA-190032> << Weblogic Messaging Bridge Adapter (XA)_eis/jms/WLSConnectionFactoryJNDIXA > ResourceAllocationException of javax.resource.ResourceException: Failed to start the connection on createManagedConnection.>
####<May 26, 2010 12:00:56 AM GMT> <Info> <MessagingBridge> <ngun015> <zlw1rdbs12-a> <ExecuteThread: '6' for queue: 'MessagingBridge'> <<WLS Kernel>> <> <BEA-200042> <Bridge RefDataCompanyBridge failed to connect to the source destination and will try again in 60 seconds. (javax.resource.ResourceException: Failed to start the connection)>
Can you please help us resolve the above issue?
Thanks,

There seems to be couple of known issues with WLS 8.1 and Tibco EMS.. Check with support whether your issue is related to any of the below:
Message bridge will stop responding and WLS has to be restarted to overcome this.
There is a known bug on WLS 8.1. Bug 8062571 is for the issue.
Should the connection be interrupted by a problem on the Tibco side, the messaging bridge never tries to reconnect. the problem can be that Tibco EMS is restarted for some reason or that the maximum number of messages that Tibco EMS can handle is reached.
Unpublished bug8066979 is available for WebLogic Server 8.1 SP6 and later
Unpublished bug8172940 is available for WebLogic Server 9.2 MP2 and later
Note you can get more info about bridge problems by following the below steps:
To debug the bridge you can enable debugging for the messaging bridge using either of the followings methods:
* Add the following lines to your WebLogic start script (before the weblogic.Server line):
-Dweblogic.debug.DebugMessagingBridgeStartup=true
-Dweblogic.debug.DebugMessagingBridgeRuntime=true
* Add the following statements to the ServerDebug entry in your configuration file (config.xml) for the server that the messaging bridge is running on:
DebugMessagingBridgeStartup="true"
DebugMessagingBridgeRuntime="true"
Once debugging is enabled for the messaging bridge, the debugging messages are sent to the server log by default. However, if you want them to appear in the Administration Console, add “DumpToConsole” to the statements show above. For example:
-Dweblogic.debug.DebugMessagingBridgeStartupDumpToConsole=true
