[jboss-jira] [JBoss JIRA] (WFLY-2778) CPU load at 99% with WildFly 8 CR1

[Matthias Richter (JIRA)]

    [ https://issues.jboss.org/browse/WFLY-2778?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12937771#comment-12937771 ] 

Matthias Richter commented on WFLY-2778:
----------------------------------------

While trying to analyze this by myself a thing came to mind I want to document here:

we are using a JRuby / Rails 4 app and had issues with a CipherError, documented here: https://github.com/jruby/jruby/wiki/UnlimitedStrengthCrypto . We had the first solution working with installing the jars. I have no idea if this affects the issue WFLY-2778, but I thought I should share this info. Meanwhile we tried the other solution but our servers end up with the cpu load after some time as well.

> After Undertow included https forwarding features when shipped with Wildfly CR1, we experienced high cpu load on our machines, reproduced on 5 different servers. Up to 3 threads are running wild, sometimes it's just one thread though. On the forum reference there are screenshots from jconsole including stacktraces of the threads.
