SSLEngineImpl is leaking memory after two or three days and can't be removed by GC

[mkassem]

Hi,

I'm using Wildfly 10.0.0, and I have changed undertow core, servlet and socket jars in modules to version 1.4.7.final. However, I'm facing a  huge increase of SSLEngineImpl each of size 16,945 bytes which leads to a memory leak after a couple of days since I'm giving my application 16GB of RAM. I think that these instances are stuck in memory because lot of users ar not performing a logout, but why they are not timing out since the timeout of the session is 60 min?

Can anyone help in solving this issue because its making me a headache.

Thanks,

do you maybe have memory dump? with GC roots?

Yes I'm using visualVM to take heap dump. After monitoring byte[] object and view the instances I found a huge number after 24 hours and it increases. I think that I don't need to give my application 16gb of ram but because of this issue I'm obliged to keep my application running for a longer time.

This is a screenshot of the nearest GC root :

Is there any bug in undertow or I have a problem in my application?
