CLOSE_WAIT connections draw 100 % cpu

I suggest you try to reproduce first with only 10 or 50 threads. Reproduction
would be successful, if you still observe continuous CPU usage in this case,
maybe less than 100%, but still noticeable.

Then in this state you take a Thread Dump (sending the QUIT signal to the tomcat
process). It will write the method stack for all threads inside tomcat to
catalina.out. Wait a few seconds an take another Thread Dump, again wait and
take a third one.

Then look at the stacks of your working threads. Anything special about the top
part of the individual stacks?
