glad to hear.
The slowest your server is the highest you should set events.delay.
In fact 1 or 2 ms (1000 or 2000 for events.delay value) should be considered as
a
maximum in order not to slow down too much requests.

Ok so I finally found why there was two requests using a browser.
There was a .js file loaded in the page, which was generated by a php script.
So the browser loading in parallel HTML and JS files, there was two
simultaneous requests to PHP.
So the conclusion is events.delays >= 1200 for me to work.
If it could help, here's my server characteristics : NANO VIA U2250 // Debian
Lenny 64bits // 2GB RAM // 160G SATA2

Ok so I got it working.
When using a simple curl request, I have to put events.delay = 1200 (minimum)
to get only 1fork/req
When using a browser... I have to put events.delay = 4000 or 5000 (I can't
remember which one was working, neither the first or the second, but I don't
think, arrived at such a value, that it changes anything) but maybe Opera &
Firefox (tested with the two, same behaviour) are opening two simultaneous
connection to the server, I don't know.
I'll try this patch on all my sites now. They're not overloaded so it won't be
burn-tests but if it can help a bit... :)
Anyway, thanks for your help.

to post a log, use pastbin or something like that.

Ok the V10 patch works :)
But it seems to be a bit fast-forking...
With a test pool with Apache2. I got 5 processes launches for a single request
(single request, I am sure there was not any other request, test vhost)
With a test nginx pool, I got 3 processes, but here it's a production website
so maybe there was 3 requests coming together, so I can't tell.
I will try the events.delay = 700 (for instance) and I'll tell you.
If I can't manage to find a way to handle the abondance of forks, I'll post a
log.
(by the way, how do you attach a file to your comment ? like a debug log ... )
