Jboss EAP 7.0.9 GA having memory issues

[paviipavii1991]

Hello,

     I am using Jboss EAP 7.0.9 GA. After using it for some time, I will face  heap memory issue.I took a heap dump and analysed it and then i observed below error.

One instance of "io.undertow.servlet.core.ApplicationListeners" loaded by "org.jboss.modules.ModuleClassLoader @ 0xaed861b0" occupies 617,096,008 (90.89%) bytes. The memory is accumulated in one instance of "java.lang.Object[]" loaded by "<system class loader>".

Keywords

org.jboss.modules.ModuleClassLoader @ 0xaed861b0

java.lang.Object[]

io.undertow.servlet.core.ApplicationListeners

Please help me to resolve the issue.

Does this involve undeploying/re-deploying the application?

[paviipavii1991]

No. The application will be up and running for whole day and at the end of the day, heap memory will be full and application will be completely slow.There  is a memory leak.If I analyse the heap dump, I got the above error. This does not involve undeploying /re-deploying. Just a restart of jboss .

Do you have any application listeners in your web application? What do they do? Do they hold on to any application specific resources? In its current form, the details that you have posted in this thread aren't enough to conclude if this is a bug in Undertow or some kind of an issue with the application itself. The profiler output you have will have additional details on which of those application listeners might be contributing to this memory usage.

We donot have any listeners in our application apart from org.springframework.web.context.ContextLoaderListener. Please do help. Feel free to ask for any information.

Can you attach the memory profile which you generated that shows the high memory usage of the listeners?
