image_manipulator.php - Problem

[farhansabir]

I have a strange kind of problem with error debugging utility. When i enabled the Debug Error Logging Utility for debugging, some files in /cache folder as as expected (small size), but others have a very large size (around 1.5GB each). This has probably something to do with the image manipulation class that we are using. But not sure why some uploads are okay, and others generate this BIG file. Image files upload so far are of a max 6MB.

Any help would be appreciated.
