With symfony 1 you cannot use session_write_close reliably. There is
a specific symfony function you call on the sfUser object to actualy
have it close properly ;) Thats why I linked my blog post to help
with that info.

Thanks Garreth for your response. As I pointed out in my original
post, though, I already tried the fixes regarding session files
locking by calling session_write_close() and also by discarding
session saving at all, by doing something like this:
function foo() {}
session_set_save_handler("foo", "foo", "foo", "foo", "foo", "foo");
Anyway, none of them worked, there's still something preventing
the requests from running.
Thanks anyway,
Gabriele

The problem is session write locking. We had the same issue
in symfony 1. I don't know how to do this for symfony 2 but I
wrote a blog post to deal with it in symfony 1. Perhaps you
can just convert this for use with symfony 2:

Hello,
I'm trying to implement long polling in a Synfony 2
project to shorten response times in a "real-time"
application I'm making. Essentially I have an ajax front
end that requests data to the symfony-driven backend
through XHR. My problem arises when I try to send a
second request to the backend while a first one is on
hang for long polling; the second request just get queued
after the first, and doesn't get processed until the
first returns.
I've googled a bit about the problem and found out that
it could depend on session files being locked (see here:
http://stackoverflow.com/questions/1430883/simultaneous-requests-to-php-script)
during requests, but getting rid of session files didn't
help (my backend is completely stateless, so it doesn't
need sessions at all actually).
Has anyone come across this problems before? I think the
problem might have to do with symfony and caching
(setting locks on cache files during requests, maybe?),
but I don't know enough of the guts of symfony itself to
find a solution or a workaround..
Thanks a lot!
