Will do... just gimme a bit to download it, I'm on dial-up here.
Extensions in use:
extension=php_mbstring.dll
extension=php_gd2.dll
extension=php_mysql.dll (compiled against libMySQL 5.0.21)
extension=php_sockets.dll
extension=php_pspell.dll
zend_extension_ts="eAccelerator.dll"
I get the same result without my build of eAcclerator 0.9.5-b2 (php
5.1.4) loaded, so that is not the cause.
Here is the memory intensive portion of the script in question:
$shipdatarow = array();
$shipcount = 0;
$filename = "shiplist.txt";
$fp=fopen("$filename","rt");
while (($shipdata = fgetcsv($fp, 1569, chr(9))) !== FALSE) {
if ($shipdata[0] == $shiprace[$WONlogonsubRace]) {
$shipdatarow[$shipcount] = $shipdata;
$shipcount++;
}
}
The file shiplist.txt is ~2.9MB in size.
I optimised it on an apache-php build on QNX I produced myself a few
years ago, as it was originally developed on a windows server when
there was no memory limit in php on windows and it needed on
optimisation to run in a reasonable memory space under my apache-php
build for QNX.
Here is the application in place:
http://www.dynaverse.net/webmap_op_sql/
however you will not be able to see the shipyards page without a forums
login on our site and a character account on the game server.
I will zip up the works for you to look at (db passwords and some
hostnames and paths removed) Much of the code is from when I first
started with php (3.x) so don't laugh too hard...
here it is:
http://www.dynaverse.net/webmap_op_sql/webmap_togo.zip
I must emphasise that I did not have this problem with exactly the same
config on php 5.0.5 so I know it is not the script or the extensions I
am using.
Nevertheless, I will test a stripped down version at home that just
opens the text file and loads a portion of it into an array. I'll do
this with no extensions loaded.
Again it will take me some time to download as I'm on dial-up at home
here.
To test it on our server I'll need to compile eAccelerator and
php_mysql against this snapshot (and it seems you've saved me compiling
an apache 2.2 module)
However the stripped down test on my home PC will get priority.

And please tell me what PHP extensions do you have enabled. Try with a
minimal config to see if the problem disappears. I rather suspect crash
has nothing to do with memory limit.
Also if possible please provide reproducing script.

Sorry, I missed your last comment before my last post.
I will indeed give that snapshot a try and report back as soon as I get
it tested!

Perhaps whatever Dmitry did here:
http://bugs.php.net/bug.php?id=36568
Changed memory use on windows, without actually enabling the memry
limit
I assume that the intention is that there should be no memory limit at
all on windows?
If that is the case, then there is one now, I just can't change it. I
know my script is not using the entire 1GB of system ram on this server
(12 MB maybe...).
When my script stopped working corresponds to the time of the change in
bug ID 36568.
I'd rather not rollback to php 5.0.5 or have to compile 5.1.4 myself
but ultimately I'll have to if the old behaviour is not restrored or
the memory limit fully enabled.
I'm not meaning to nag here, just filling in more info that I hope will
be helpful. I'll find a solution one way or another but it is my hope
that the old behaviour of memory use on windows will be restored or the
memory limit will be fully enabled, whatever you guys think is
appropriate.

Please try using this CVS snapshot:
http://snaps.php.net/php5.2-latest.tar.gz
For Windows:
http://snaps.php.net/win32/php5.2-win32-latest.zip
Default php does not have any memory limit.
Please use php5handler2_2.dll if you're using apache 2.2

Ah, thanks.
The thing is, this memory intensive script of mine worked fine on php
5.0.5, but its output is truncated on php 5.1.2 and up. It generates no
other errors.
As well, our upload scripts used to allow a 40 MB file upload on php
5.0.5 and previous versions. I have not tested whether it still does,
but I assume it is affected by the changes in memory limit behaviour on
windows.
Something else has changed with respect to memory use on windows.
Perhaps the harcoded memory limit of php has been reduced?
If I build 5.1.4 for Win32 from source myself can I enable the memory
limit or change the hardcoded limit? (I suspect from your comment I
can)
Thanks again for your attention to this matter, it is much appreciated.
