Srivathsan Agaram Venkatavaradhan created WFLY-4617: ------------------------------------------------------- Summary: Huge garbage created at regular intervals in Wildfly 8.2.0.Final Key: WFLY-4617 URL: https://issues.jboss.org/browse/WFLY-4617 Project: WildFly Issue Type: Bug Affects Versions: 8.2.0.Final Environment: Centos 7, JDK 7 Reporter: Srivathsan Agaram Venkatavaradhan Assignee: Jason Greene Huge garbage is created in wildfly every couple of minutes. Though Full GC is able to reclaim memory, this causes frequent full gcs as heap is getting occupied due to the increase in number of objects . I can reproduce this issue in 60 users Jmeter loadtest. This was not the case in Jaboss 7.1.1Final. After analyzing heapdumps, I can see huge char arrays are created and they are not garbage collected by Minor GC. Incoming reference for the char array suggest that they have valid reference to io.undertow.servlet.spec.HttpServletRequestImpl. "org.apache.struts.tiles.ComponentContext" is kept in attributes Map by io.undertow.servlet.spec.HttpServletRequestImpl. org.apache.struts.tiles.ComponentContext contains a big char array. We suspect issue with undertow. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
