Hi,

As far as I see these threads are not blocked, basically all of them (before
they are removed due to inactivity)
are showing similar thread dumps to this one:

So if server threads are not blocked and idle in the thread pool, it's
unlikely that the server will not respond.
I'm guessing you have some other problem.
We are using a tsung master/client setup across multiple VM's to generated
the load.
Even if those have a problem, If I start a new client for a different
machine, it should not be affected unless
something on the server is blocking. The only thing I get is a client side
timeout.
Can you take a server dump as explained here:
http://www.eclipse.org/jetty/documentation/current/jetty-dump-tool.html
?
Here a dump (collected via jmx):
