I've had a client recently decide to begin using the Watermark feature for their product images. I've encountered an issue, however, with the watermarks completing for all products. What seems to be happening is that while many of the images are generated with the watermarks, a lot never finish and I just get blank or corrupted images appearing in place of the actual image. The site has a lot of images, so I've even tried unpublishing most, just applying watermarks to 20 or so at a time, and the same issue crops up even then. I don't have a clue as to why, but it seems like the process just stops and many images just never complete the process.
