[jboss-jira] [JBoss JIRA] (WFLY-6583) Session leak on SmartOS hosts

Michael Noack created WFLY-6583: ----------------------------------- Summary: Session leak on SmartOS hosts Key: WFLY-6583 URL: https://issues.jboss.org/browse/WFLY-6583 Project: WildFly Issue Type: Bug Components: Clustering Affects Versions: 10.0.0.Final, 9.0.0.Final, 8.2.0.Final Environment: CentOS 7 or SmartOS instance using Joyents Infrastructure/Bare metal container. [root@979638eb-b45c-45b3-9fdb-d7f48276e4ef /]# java -version java version "1.8.0_77" Java(TM) SE Runtime Environment (build 1.8.0_77-b03) Java HotSpot(TM) 64-Bit Server VM (build 25.77-b03, mixed mode) [root@979638eb-b45c-45b3-9fdb-d7f48276e4ef /]# uname -a Linux 979638eb-b45c-45b3-9fdb-d7f48276e4ef 3.10.0 BrandZ virtual linux x86_64 x86_64 x86_64 GNU/Linux [root@979638eb-b45c-45b3-9fdb-d7f48276e4ef /]# cat /etc/issue \S Kernel \r on an \m Reporter: Michael Noack Assignee: Paul Ferraro Priority: Minor When running Wildfly 8.2.0-Final, 9.0.0-Final or 10.0.0-Final in domain mode using the full-ha profile some sessions never get closed when running on SmartOS or a BrandZ kernel on SmartOS. The amount of unclosed sessions rises slowly. I've been keeping track of this issue for almost a year now and handled it by restarting the entire cluster at first. When registering a HttpSessionListener and logging any sessionCreated(HttpSessionEvent se) and sessionDestroyed(HttpSessionEvent se) one can cleary see some sessions never generate the sessionDestroyed event. The problem disappears when running the very same setup on a KVM instance of CentOS 6 or 7 (regardless whether the KVM host is SmartOS or Linux). -- This message was sent by Atlassian JIRA (v6.4.11#64026)
