Is probably not a real memory leak and is just the zend memory manager complaining about having to cleanup after APC.

Sad to say, this is to be expected in most cases as APC cannot divine when the class is ready to be thrown away from local memory and keeping track of all such memory allocated in extension land is pointless when zend mem allocator already does that albiet with warnings.

Thanks for your reply. But as I already said, in this code there are NO CLASSES at all. Not one. Everything is "basic" php code, with a bunch of global variables. No classes, no OO code in this one at all. Do you think that the explanation you outlined still account for these "memory leaks"?

Like gopal says this really isn't a big deal, but if you can give me a super simple repro of this and verify it works on the latest release I can probably take a look at it.  -thx

Thanks, but this problem is long gone. I use Apache 2.2 and APC 3.0.16 now, there are no more memory leaks reported in the log files.
