This problem reveals a memory limit bailout problem.
Even if PHP exhsusted memory, script does not exit.
PHP logs following logs many times. (Linux/PHP4.1.0, without output buffering)

Note: this seems to be the same problem as #14222, but I can't seem to append stuff to
someone elses bug so...
This is something I first noticed when I upgraded from XP RC1 to WinXP Final, when
using PHP 4.0.6. I upgraded to 4.1.0 today, and it doesn't solve the problem.
The php apache module doesn't seem able to handle outputting moderate to large sized
pages.
I have been able to reliably reproduce the problem with the following script:
<?PHP
set_time_limit(900);
for ($i = 0; $i<1000000; $i++){
print "This is line number " . ($i+1) . "<br>";
}
?>
Viewing this page with internet explorer causes it to go into an almost endless loop
of relaoding the page. It will display the first few 'this line is number...' and
then will reload the page over and over. On some sessions IE will eventually show
it's 'The page cannot be displayed' page, and sometimes it will just reload
indefinitly.
Viewing this page with Mozilla/Netscape doesn't have the same effect. Mozilla doesn't
go through the reload loop, but will not show the page as it should either. There
will be unexplained (no errors) jumps in numbers/missing output such as:
This is line number 2368
This is line number 2369This is line number 2517
This is line number 2518
But the errors in output don't occur in the same spot each time. And evenutally (well
short of 1,000,000 lines) the output will just stop with no error, often in mid line.
I have found that adding 'flush();' just after the 'print "This is line...' seems to
fix the problem.
