I got a problem when benching SPECjEnterprise2010.
The http threads in the thread pool all waiting for http input.
tack trace:
java.net.SocketInputStream.socketRead0(Native Method)
java.net.SocketInputStream.read(SocketInputStream.java:146)
org.apache.coyote.http11.InternalInputBuffer.fill(InternalInputBuffer.java:731)

java.lang.Thread.run(Thread.java:679)
org.jboss.threads.JBossThread.run(JBossThread.java:122)

The executor was idle waiting while thousands of requests were not served, queued and never served in the end.
I don't know which configuration caused this problem.
My configuration about web is:
        <subsystem xmlns="urn:jboss:domain:threads:1.1">
            <unbounded-queue-thread-pool name="JBossWeb">
                <max-threads count="200"/>
                <keepalive-time time="10" unit="second"/>
            </unbounded-queue-thread-pool>
        </subsystem>
        <subsystem xmlns="urn:jboss:domain:web:1.2" default-virtual-server="default-host" native="true">
            <connector name="http" protocol="HTTP/1.1" scheme="http" socket-binding="http" executor="JBossWeb" max-connections="3000"/>
            <virtual-server name="default-host" enable-welcome-root="true">
                <alias name="localhost"/>
                <alias name="example.com"/>
            </virtual-server>
        </subsystem>

If I use the defaut executor, there will be thousands of threads created.
Most of the threads does nothing but waiting i/o.

Could anyone tell me what can lead to this problem?
