Unknown error when upload folder too big.

[Rinkana]

I have an image folder with with a few hundred images. However when i use the filebrowser it returns an 500 server error and does not finish building all thumbs. The browser self only returns "unknown error"

I use kcfinder 2.54 and the latest Ckeditor.

Could you try with 2.51? http://sourceforge.net/projects/kcfinder/files/KCFinder/2.51/

Same issue, might want to note that Chrome tells me that the popup has crashed (only the first time building the thumbs) and then returns the error. Where FireFox just tells me unknown error after a while.

However they all return an 500 error.

Is there any way to force building the thumbs while i am not in the browser?
Edit: Our error log shows no errors.

Same issue here, with version 3.12

Any update on this issue? I'm kind of stuck right now without a solution.

What value you have set for memory_limit?

Maybe some image gets stuck and stops the process, since for a picture 2MB I think you may need a value greater than 64M. Many of the problems are because of that.

If at least some thumbs are generated, it is a good idea to move the rest of the images to another folder and move back again gradually, until you find the image that causes problems. From there you can get more information. This way you can corner the cause.

Hi

The problem with large folders appears because if there are no thumbs the system tries to generate all thumbs in one run.

I changed the code to ignore the generation and i'm generating the thumbs when they are requested one by one.
