Jetty container hangs after some time

Hi.

I am using Jetty 8.0.4 stable release binary.

During my testing, I am pumping a load of 100 HTTP requests per second.

After sometime, Jetty stops responding to the incoming requests and hangs. The first few hundred requests are processed in a normal fashion, and later the Jetty container hangs.

The details of my enviornment are as follows -

Servers: HP DL-380 G7 series with 16 GB RAM, RHEL 5.4, 64-bit OS.

JAVA_OPTS: JAVA_OPTS="$JAVA_OPTS -Djava.net.preferIPv4Stack=true -Xms8192m -Xmx8192m -server -XX:+UseNUMA

Network speed - 1 GIG switch.

Upon executing thte netstat commond on RHEL, I observed that there are many TCP connections in TIME_WAIT state.

In my Jetty handler code, I am returning a response and not hogging the threads.

I could not obtain a thread dump, as I was unable to connect to the Jetty process using JCONSOLE (all sockets were occupied as mentioned earlier).

However, I am attaching the netstat command(netstat -p <pid>) output with this post.

Please, let me know the steps to debug this issue, and I will help in getting to the root cause of this issue.
