random red cross error

betatest

Hello ;

After amny tries, i didn't success in debuging my complex app.

I have a script that generate a lot of dynamic images (arroud 1500) throw GD via PHP4/mySQL.

when the i run the code, there are some random images that are a red cross image.

It doesnt' came from the PHP timeout.
It is the same under apache 1.xxx and apache 2.xxxx
it is the same under linux and windows.
it is never the same images.

Last point the datas are heavy and a mySQL table is 45 Mbytes.

I didn't manage to find from where it come from.

thank you in advance.

Is the image data stored in the database?

betatest

no it is generated from data in the database with GD.

The only thing I can think of at this moment is the browser is busy fetching all 1500 images that it times out if it doesn't get an image coming in within a specified amount of time. Have you tried the page with half that many images?

Yeps i have try this solution and it works without problems...

but i need all the images on one page one one script.

I'm thinking thats too many for the browser to handle. Either scale back or combine the images. Or add more server hardware (which I'm not sure would solve much of anything).

already tried to improve the hardware and id didn't work . It doesn' t came from the CPU...

Thank you anyway.
