Hi Team, We were doing testing of Qpid JMS client for failed scenario. We are receiving message as client acknowledgment mode.
Scenario - Receive message but do not acknowledge the message. Issue - Memory is not getting released by Qpid on failed Scenario We could have this scenario in prodcution. We received the message, but failed to process that message, so there will no aknowledgment. As we are acknowledging only one success scenario. Please find attached sample TestQpidRcvOnly.java, Total_Memory.PNG, Sampler_Per_Thread_Allocation.PNG, Out_Of_Memory_Error.log . Steps to reproduce this issue --> 1. Provide Correct details of QUEUE_NAME, SBUS_NAME, USERNAME, USERNAME in TestQpidRcvOnly class 2. Publish 200000 message on QUEUE_NAME, from any utility 3. Start the TestQpidRcvOnly class and keep it running 4. Open JVisualVM and have a look on Heap memory 5. Wait for 20m, you can see memory consumption continously increasing 6. You can see Out Of Memory Error on exhaustion of defined Max heap Memory. Could be 1hr depends on Max Size 7. You can have a look on Sampler--> Memory -->Per Thread Allocation, you can observe that Qpid thread is consuming more that 98% memory. Consumption is OK but it is not releasing the memory, which is the cause for Out of Memory Error. Using -- Java 8, Azure ServiceBus, Qpid-jms-client-0.48 Could you please take a look on this issue.
