The problem looked like v3 was not releasing the AJP connections correctly or something alike so that mod_proxy_ajp / mod_jk could reuse the connections. But this was simply a symptom.

In v3 when you create a new JK listener, the thread pool is set to http-thread-pool by default. The default size of this pool, if I recall correctly, is 5! When using Apache in prefork mode, the size of the thread pool should be at least the value of MaxClients when using mod_proxy_ajp or mod_jk.

Sorry for the trouble.
The default max-thread-pool-size was reduced to 5 since it was decided
to be enough due to the NIO nature of the grizzly.
V3's default domain.xml also defines "thread-pool-1" with
max-thread-pool-size=200 as it was in v2.
<thread-pools>
<thread-pool name="http-thread-pool" />
<thread-pool name="thread-pool-1" max-thread-pool-size="200" />
</thread-pools>
You can create a jk-connector with "thread-pool-1" rather than using the
default http-thread-pool if you need to increase the max-thread-pool size.
create-network-listener .... --listenerport 8009 --threadpool
thread-pool-1 --jkenabled=true jk-connector
Sun GlassFish Enterprise Server v3 Reference Manual [1] mentions that
the default thread pool is http-thread-pool.
