We have exactly the same problems, I've tried the tuning options in the links above for a couple of months, but the problem persist.
I'll try the timeout setting next; com.sun.enterprise.web.connector.grizzly.readTimeout=5000
We can't update to glassfish v3 just yet, so that's not an option for us at this time.
Version info:
Gentoo 64bit: linux kernel 2.6.31-gentoo-r6
Sun GlassFish Enterprise Server v2.1.1 ((v2.1 Patch06)(9.1_02 Patch12)) (build b31g-fcs)
Java(TM) SE Runtime Environment (build 1.6.0_18-b07)
running in a VMWare vSphere environment.
The server usually begins to consume cpu before the https-hang, and, using jconsole with top-threads plugin:
http://lsd.luminis.nl/top-threads-plugin-for-jconsole/ I see a httpSSLWorkerThread-443 using 100% cpu that has the following stack:
sun.nio.ch.EPollArrayWrapper.epollCtl(Native Method)
sun.nio.ch.EPollArrayWrapper.updateRegistrations(EPollArrayWrapper.java:246)
sun.nio.ch.EPollArrayWrapper.poll(EPollArrayWrapper.java:209)

sun.nio.ch.SelectorImpl.lockAndDoSelect(SelectorImpl.java:69)
sun.nio.ch.SelectorImpl.select(SelectorImpl.java:80)
-> seems to be from here and up the busy-loop is running <-
