Salut,
(adding Comet to the title so it will makes easier for peoples to search).

Hum...no simple to debug :-)
[1] I suspect mod_proxy isn't closing the connection immediately ( I
could be completely wrong) and might delay it.
[2] Can I send you a Grizzly patch that contains debugging information?
Inside that patch I will add extra logging to see if the connection is
really closed. If the connection is closed, I suspect there is somes
bytes that are sen by mod_proxy, and Grizzly thinks this is a pipelined
http requests. In that case, and since Grizzly Comet supports
asynchronous I/O (read and write), the Comet engine might think this is
an event for your CometHandler, but since you haven't registed to get
notified, the event goes nowhere.
I unfortunalty don't have time today to install your config, but if you
cannot patch GlassFish I will try next week.
Thanks
