------------------------------------
Summary: Wildfly eats the CPU up to 100% and does not respond
Key: WFLY-7292
URL: https://issues.jboss.org/browse/WFLY-7292
Project: WildFly
Issue Type: Bug
Affects Versions: 10.1.0.Final
Environment: Ubuntu 14.04, Linux 3.19, Oracle Java 8u91 64-bit
Reporter: Krisztian Kocsis
Assignee: Jason Greene
Hi!
I have a JAX-RS application and after a lot of load, one thread eats up the CPU (100% usage) even when the load test app is terminated, and never drops down until I restart the app server.
It causes me a lot of headeches because it totally makes the app server unusable until I restart, but the users unable to use the app in the meanwhile.
I'v attached the stack trace but I unfortunately don't see anything according to my knowledge.
Please help me, I can provide more information if necessary.

[JBoss JIRA] (WFLY-7280) getSession() Always Creating HttpSession Problem

> Key: WFLY-7280

> Project: WildFly
> Issue Type: Bug
> Components: Web (Undertow)

> I have a login application called cas.war. I store the captcha code in session. This application has been running smoothly in JBoss7 and Tomcat7. But when I tried to migrate to wildfly10, I found the captcha code will always be null. I dug a little deeper, and found out that the server is creating new session each time I post a request(the JSESSIONID cookie changes on every request). I traced the code and pinned down the problem on this location (as of undertow-servlet-1.4.0.Final-sources.jar ) :
> {color:#f6c342}io.undertow.servlet.spec.ServletContextImpl.java, method getSession:{color}
> {code:java}
> public HttpSessionImpl getSession(final ServletContextImpl originalServletContext, final HttpServerExchange exchange, boolean create) {
> SessionConfig c = originalServletContext.getSessionConfig();
> HttpSessionImpl httpSession = exchange.getAttachment(sessionAttachmentKey);
> {code}
> while
> sessionAttachmentKey = {color:#f6c342}io.undertow.util.SimpleAttachmentKey<io.undertow.servlet.spec.HttpSessionImpl>{color}
>
> the exchange.attachments map will only contain one such key: {color:#f6c342}io.undertow.util.SimpleAttachmentKey<io.undertow.server.session.InMemorySessionManager$SessionImpl>{color}
> thus the server will create new session once request.getSession() is called, regardless one session exist or not.
> And please have a look at the relate class InMemorySessionManager too.

[JBoss JIRA] (WFLY-6173) Classes not unloaded after undeployment
by David Maes (JIRA)
[ https://issues.jboss.org/browse/WFLY-6173?page=com.atlassian.jira.plugin.... ]
David Maes commented on WFLY-6173:
----------------------------------
[~mkouba] thank you for the quick reply.
Our memory issue will probably not be caused by the jackson problem. So I think we'll have to do some investigation on our own.
> Classes not unloaded after undeployment
> ---------------------------------------
>
> Key: WFLY-6173
> URL: https://issues.jboss.org/browse/WFLY-6173
> Project: WildFly
> Issue Type: Bug
> Components: CDI / Weld
> Affects Versions: 8.2.0.Final, 10.0.0.Final
> Reporter: Joey Wang
> Assignee: Martin Kouba
> Priority: Blocker
> Attachments: memory-leak.zip, memory-leak_New.zip
>
>
> I deployed a small web application with one single JSF and one managed bean, accessed the page and then undeployed the application. I found the classes of this application had never been unloaded via monitoring with Java VistualVM, also using '-XX:+TraceClassUnloading' JVM option proved the classes not unloaded.
> Then checking the heap dump of it, I found there were instance for each enum item (the managed bean has one enum type field, which is always initialized when the managed bean constructed) and one array instance including these enum instances.
> Please refer to the attachment for the same application. I started to verify the classloader memory leak issue because we found hot redeployment of our real application swallow some memory each time, then after lots of redeployment the server was short of memories.
