WildFly 8.2.0.Final runs into OOME quickly ------------------------------------------ Key: WFLY-4962 URL: https://issues.jboss.org/browse/WFLY-4962 Project: WildFly Issue Type: Bug Components: Web (Undertow) Affects Versions: 8.2.0.Final Environment: WildFly 8.2.0.Final Linux/Unix jdk1.8.0_45_64bit Reporter: Rakesh K. Cherukuri Assignee: Remy Maucherat Priority: Blocker Attachments: test-oom.war, visualvm.png Issue: Wildfly runs into OOME with a basic servlet Cause (possible): Data set in request as attributes is not getting freedup. It eventually eats up heap leading to OOME Please note that for the reproduction scenario i have attached a WAR with a simple servlet. But its the same issue in our production build too. We upgraded to Wildfly 8.2.0 Final few weeks back.
