Gary Tully created AMQ-6824: ------------------------------- Summary: PrefetchExtension growth with transacted consumers Key: AMQ-6824 URL: https://issues.apache.org/jira/browse/AMQ-6824 Project: ActiveMQ Issue Type: Bug Components: Broker Affects Versions: 5.15.0 Reporter: Gary Tully Assignee: Gary Tully Fix For: 5.16.0
With a transacted consumer on either a topic or queue the prefetch extension increments only. This leads to flow control failing b/c the subscription is never full. Messages can accumulate on the subscription dispatch channel if the consumer is blocked or slow. As a result, memory usage limits can be exceeded for topics. There is a similar issue with client_ack mode and prefetch. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
