> Key: CAMEL-5086
> URL: https://issues.apache.org/jira/browse/CAMEL-5086
> Project: Camel
> Issue Type: Bug
> Components: camel-spring
> Affects Versions: 2.9.1
> Environment: Apache Tomcat 7.0.26
> jdk 1.6.0_26
> CentOS:
> Linux version 2.6.18-238.el5
> Reporter: Dan Richelson
> Assignee: Claus Ibsen
> Priority: Minor
> Labels: leak, memory, memory_leak, permgen, spring, tomcat, war, webapp
>
> Steps to reproduce:
> 1. Create a new camel web project (based on instructions here: http://camel.apache.org/camel-maven-archetypes.html ):
> mvn archetype:generate -DarchetypeGroupId=org.apache.camel.archetypes -DarchetypeArtifactId=camel-archetype-web -DarchetypeVersion=2.9.1 -DarchetypeRepository=https://repository.apache.org/content/groups/snapshots-group
> 2. Build the new project:
> mvn clean install
> 3. Copy .war file in target/ to tomcat's webapps directory.
> 4. Reload webapp (easiest way is to touch the .war file)
> 5. If you are using a profiler, you will see that the permgen space increases on every reload (the previous webapp's classes don't get unloaded)
> 6. Eventually the webapp container will crash with a permgen out of memory error.
> Workaround: restarting the webapp container will reset the permgen space.
> Removing the Spring nature of the project makes this go away, so it could be a problem with Spring itself.
> This also happens when using Jetty7, so I don't think it is a problem with the container.
