[jboss-jira] [JBoss JIRA] (WFLY-898) SharedLocalYieldingLockManager.LocalLock

SharedLocalYieldingLockManager.LocalLock ---------------------------------------- Key: WFLY-898 URL: https://issues.jboss.org/browse/WFLY-898 Project: WildFly Issue Type: Bug Security Level: Public(Everyone can see) Components: Clustering Reporter: MJ Kim Assignee: Paul Ferraro Hi, Recently my system has been in the QA. (includes Stress test, Endurance test) During the endurance test, I found that the heap space was getting exausted, and not removed after full gc. When the heap space got close to 90%, the gabage collection was happend every 2 min, and my system was stopped reponding. The heap space was not cleaned up, nevertheless I ended the test (no request during a few hours) I downloaded some heap dumps, and found that the SharedLocalYieldingLockManage.LocalLock() resided much of heap space. (above 60%) I think the session expiration doesn't operate porperly. If the SessionBasesClusteredSession class raises the expiration signals with "LocalOnly=True", the lock would not be removed. Addionally, I reviewed our source code and did a leakage discory test, anything was matter. Here is my environment. If you want to see my standalone.xml, please post a reply thread. <Cluster> - 8 JVM (4 machine, each 2) - JDK : 1.6u31 - OS : Amazon Linux 64bit - JGroups : FILE_PING (The shared storage is GlusterFS volume) - Infinispan operation mode : L1 + Distribution / ASYNC / expiration 1min - Session handling : web.xml (expiration every 1min) (Originally our setting was 30 min. Beacuse the load generator was sending too many requests with new session, I lowered the threshold to 1min) - Source code : 7.1.3 Final tag (downloaded from Github)
