Re: [HACKERS] Re: PHPBuilder article -- Postgres vs MySQL

Basically, after so many people connect and disconnect, the PHP doesn't
reuse/drop old connections so you maximum amount is reached. You'd get to
the point where no one is connected, but one another person would try to and
it would come back with an error saying no connections available.

I am unaware if anything has been posted to PHP about it.
