PHP does have a "garbage collector", but this may be an issue with an inability to perform gc due to a circular reference issue in Propel. If I understand it, the problem happens in this kind of case:
Table A has a reference to Table B, thus the propel om has classes A and B, which have references to each other. Let say you something like: $a = new A(); $b = new B(); $a->setB($b); (under the covers, $b will now also have a reference back to $a) Once $a and $b go out of scope they should be marked to be freed up by the garbage collector. But I think what happens is that when the garbage collector sees $a it sees that $b has a reference to it, and vice versa. So neither gets unallocated. I saw that the propel folks did some work on this, but I haven't gone through their code. This may also be an environment related issue. I have had the same dataset working for months on Vista, on my laptop where I've been developing my app. My phpinfo() on Vista says max memory is 128M, the same as the Linux box of my hosting provider. I never had any problems until I tried this on Linux, and even on Linux it's intermittent. I also see the provider is running PHP 5.2.9, whereas I'm running 5.2.8 on my laptop.
