Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere Message Broker V6.x. * **************************************************************** * PROBLEM DESCRIPTION: Redeploying a flow which is currently * * active (a hot deploy) may result in * * the deployment hanging. * **************************************************************** * RECOMMENDATION: * **************************************************************** When a flow is redeployed the Configuration Manager sends a message to the Broker's Admin Agent which in turn instructs the Execution Group to delete and then replace the affected nodes. If the flow is running when the redeployment occurs then its threads are stopped, their resources are released and the threads returned to a thread pool for re-use. The problem is that the first thread is not properly cleaned up and this can lead to a situation in which the deployment hangs waiting endlessly for that thread to release its resources.
Problem conclusion
WebSphere Message Broker has been modified so that the problem no longer occurs.
