Hi,
It seems that my problem is different...
For me, when I am testing my program on Win2000 platform I keep watching the memory usage report in my task manager. I only notice the Apache process continues to increase its memory usage, from 5MB to 6, 7,
... then 15MB, after tens of PHP page accessing ---- however, no such 'fatal error' as you describe occurs on my PC.
I tried some static HTML page and even some very simple 'hellow world' PHP programs, they are all ok, don't have this problem.
