still occurs in php5.3-201102150730
When php eats much memory ( ~ 100M it seems there are some memory leaks
in the program? ), the problems occurs more easily.
In the program, I have a big loop to process thousands of web sites,
I use DOM/SimpleXML to parse xml data from every site and use GD to
process some images.

It seems no problem in 5.3
------------------------------------------------------------------------
[2011-01-26 06:39:03] ahar...@php.net
PHP 5.2 is no longer supported.
Does the same problem occur in PHP 5.3.5?
