Jeff Mesnil created WFLY-8882: --------------------------------- Summary: Artemis client uses unbounded threap pool Key: WFLY-8882 URL: https://issues.jboss.org/browse/WFLY-8882 Project: WildFly Issue Type: Bug Components: JMS Affects Versions: 11.0.0.Alpha1 Reporter: Jeff Mesnil Assignee: Jeff Mesnil Priority: Critical Artemis client thread pool can be configured using the messaging-activemq subsystem's global-client-thread-pool-max-size attribute (introduced in 11.0.0.Alpha1). By mistake, the default value of this attribute was set to -1 (through the ActiveMQClient.DEFAULT_THREAD_POOL_MAX_SIZE constants). This means that unless configured otherwise, the Artemis clients running in the app server (e.g. MDB code) will use an unbounded thread pool. The correct configuration is to *not* have a default value. If that's the case, Artemis will determine the size of the pool depending on the number of processors (8 * Runtime.getRuntime().availableProcessors()) -- This message was sent by Atlassian JIRA (v7.2.3#72005)
