Recently, I used Asynchronous servlets and AsyncListeners on my project.But when it runs on WildFly.8.1.0.Final,a problem appeared as following:

So i know there maybe occur connection leak on WildFly, and i made a test as follow:
I use apache's jmeter to test this project,i use 50 users to request it,then use "lsof -p pid | can't identify protocol | wc -l" to find is there have “can't identify protocol”,the number is 0.But when i stop the request,there appeared lots of "can't identify protocol",the same phenomenon appeared on wildfly-9.0.0.Alpha1 and wildfly-8.2.0.Final but not appeared on tomcat.So i'm doubt that this is wildfly's bug,Is there anyony encounter this problem and tell me how to solve it.
Moreover, i found a issue is like above problem:
[WFLY-3652] Network connection leak - JBoss Issue Tracker
but don't think they are the same probem,because it say the problem alrendy was fixed in wildfly-9.0.0.Alpha1,but above problem wasn't fixed when i test my project on wildfly-9.0.0.Alpha1.
Who can help me solve this problem? thanks!

[JBoss JIRA] (JGRP-1914) S3_PING doesn't work with S3 buckets created in Frankfurt region
by Thorsten Hoeger (JIRA)
[ https://issues.jboss.org/browse/JGRP-1914?page=com.atlassian.jira.plugin.... ]
Thorsten Hoeger commented on JGRP-1914:
---------------------------------------
Is there any chance that IAMProfileAuth will be included as well? When running instances in AWS it is best to assign IAM roles with access to the bucket, but JGroups ignores this.

> I tried to use S3_PING with access and secret key pair. However, I got 400 (Bad Request) error. After some investigation, I found that modern S3 buckets created in Frankfurt needs amazon v4 authentication, which needs hmac-sha256. But now S3_PING supports only hmac-sha1, so I see no way to use S3_PING with buckets in Frankfurt region.
