Messages are stuck in a Queue that is configured on HornetQ ----------------------------------------------------------- Key: WFLY-9639 URL: https://issues.jboss.org/browse/WFLY-9639 Project: WildFly Issue Type: Bug Components: JMS Affects Versions: 9.x.x TBD Environment: RHEL 7.2, JDK 1.8_144 Reporter: Rajendra Mallampati Assignee: Jeff Mesnil We use WildFly 9.0.2 for hosting our web application and it has both real time and batch processing components. One of the functions supported on the web includes uploading a file with a number of lines any where from 1 to 10K, If the file is valid (virus scan etc passed) it is parsed into that may messages and published to a queue. Each message will have two counters total number of messages that are published to the queue, and the message number. The consuming side is implemented using Spring DefaultMessageListenerContainer (DMLC) with a concurrency of 50 and maxConcurrency of 75. The listeners that implement MessageListener interface are integrated into DMLC. sometimes, if the producing side published 100 messages the consuming side only receiving 98 (per say) and gets stuck because two more messages should be in the Queue. Those two messages are not delivered and don't know where they are going. We tried even persistent Queues and the result is same (getting stuck). This is happening in production and any insight into this issue is highly appreciated. Here are the software details: App server : Wildfly 9.0.2 HornetQ : 2.4.7 JDK : 1_8_144 If you need additional details I will be very glad to provide. Thanks Rajendra
