I'd also try opening all the image files in some Apple-related graphics programs (e.g., Preview, QuickTime Player, etc.) in order to determine if it's system-wide or some combination in your own application; of course, there are other factors that would be involved in using these, but since

As I mentioned in my case, the images load fine when running through XCode, but not as a standalone binary. So, I guess the images themselves are fine. As producing an isolated test case scenario is going to be prohibitively difficult in my case, all I would like is a way to detect this happening

Hi James, Nicholas, I still bet it's someone holding too many file descriptors open. Nicholas, when you said this, but I have forced the thumbnail creation to have at most 10 files opened at the same time, what did you mean? You can see what files your process has open using the lsof command

Indeed, for me, this is related to file descriptors. While it's still unclear to me exactly where the problem lies, some quick fiddling with opening the files as NSData and creating images from those appears to be bearing fruit. Thanks! -j On Fri, Aug 8, 2008 at 5:51 PM, Jean-Daniel Dupas [EMAIL

Well, I can't speak for James, but I have forced the thumbnail creation to have at most 10 files opened at the same time, and it doesn't make a difference... I could understand a memory allocation issue, if the app didn't take roughly 100 megs of RAM. And besides, I can see there's a

Hi Nicolas, David, I'm having the exact same problem. Loading collections of small images (jpeg in my case). The only slight difference for me is that if I run my application under XCode (Debug build), I don't get any errors. All of the images load fine. However, when I run the (Debug) binary,

Couldn't tell either of you why your having issues without seeing code, and probably not even then, but this is probably worth a bug report. On Aug 6, 2008, at 1:52 PM, James Trankelson wrote: I'm having the exact same problem. Loading collections of small images (jpeg in my case). On

Off the top of my head, with a number of files being opened so high and relatively close to the value you get from getrlimit with a parameter of RLIMIT_NOFILE, I'd suggest checking to see if that's the problem. Hi Nicolas, David, I'm having the exact same problem. Loading collections of small

David, the images are GIFs, roughly 40KB each, 200x100 (or 100x200). Nothing fancy. On 05 Aug 2008, at 01:05, David Duncan wrote: What types of images are you trying to load? -- Zino ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com)

Hey all, I have this app that constantly updates a series of thumbnails in the background for a Cocoa view. When I have less than, say, 40 items in there, there is no problem at all. If I add three times that many elements, CGImageSourceCreateWithURL fails with error -11 Now, I know it's
