I do not know what PHP7 is, but i got this error with PHP 5.4 preloaded into Mac Os X 10.8. I am not
contributing to PHP development, so it is not one of those development versions i think.

I think you probably have this issue with released PHP versions still, not with master(PHP7).
Could you verify it?

Description:
------------
Hello,
I think I have a problem that I really could not fix and think that it is a bug.
The thing is that I have a web site for messaging that enables logging in using Zend\Session. Now
think that on one browser tab I am logged in, then the web client makes calls to the server every 10
seconds to check if there is any new messages (via ajax calls). At this time from another browser
tab, if i run a second call to server to logout it gives this error:
2014-08-25T21:31:07+03:00 WARN (4): <pre>Error: session_regenerate_id(): Session object
destruction failed
If I close the first tab login and try again this error does not occur. I use the free usage tier of
AWS, so the server is really slow. I think that's why I see this error because a simple server
call can take a few minutes.
So the summary is that if there are two or more calls to the server at the same time and one of them
tries to destroy the session, PHP raises errors because somehow it cannot handle all these requests
and session destruction.
And I must note I tried the same thing when the server runs fast (you know these servers sometimes
run fast and some times really slow) and at that time this error does not happen. I think that is
because if the server runs fast, then the probability is much lower that the both run at the same
time.
Hope I am not wasting you time.
Best regards,
Mucahit
