I have here more or less the same problem. When in an event and after selecting one photo. The whole system freezes. In the library are 600 events and 15000 photos.
Only a hard restart with the power button brings everything back to life. Machine mac pro. On my imacs I have no problems but libraries are half smaller in seize.
I've found a process that can reproduce this 100% of the time.
1. Create a new book (or edit an existing).
2. Enter full screen mode.
3. Add one of the map pages.
4. Start adding places to it.
One my computer during adding the first or second place the processor jumps to 100% and iPhoto stops responding.
I didn't need to login remotely to reboot it, hitting command tab will show the dock and menu bar (even though you can't make any windows appear above the iPhoto window) and you can force quite iPhoto. I have no idea what it freezes doing. The system processor usage is at about 30% and the iPhoto consumes the rest.
Do you know if you have a Mac with an NVIDIA based card? There is a large thread, +not directly related to iPhoto+, about NVIDIA drivers freezing systems:
Myself and at least one other person have seen this happen even more frequently with iPhoto '11.
You won't see the error message in the Console All Message log. To see it, you open Console, expand FILES, expand /private/var/logs/, and look at kernel.log.
If around the time of the system freeze and you see errors like:
*NVDA(OpenGL): Channel timeout!*
*NVDA(OpenGL): Channel exception! exception type = 0x6 = Fifo: Parse Error*
Then you are likely having a driver issue that has gone on for a while with NVIDIA based Macs.
Not much you can do. Hopefully it just freezes the system for a short time and doesn't require a restart.
Hm.. I do not see this exact error message; it also looks like the problem is different because the way you describe it, your system can actually recover. In my case, I have not seen it recover and so far a reboot is the only way to gain access to the screen again.
But you did bring me on a path to some sort of error message. Right around the time of the crash I see, in that same system.log:
Oct 22 19:50:44 imac kernel: ** Device in slot: SLOT--1 **
Oct 22 19:50:44 imac kernel: ** GPU Debug Info Start **
Oct 22 19:50:44 imac kernel: 0x00009583
Oct 22 19:50:44 imac kernel: 0x000000d6
...around 800 lines skipped...
Oct 22 19:51:01 imac kernel: 0x00000000
Oct 22 19:51:02: --- last message repeated 47 times ---
Oct 22 19:51:02 imac kernel: ** GPU Debug Info End **
Oct 22 19:51:13 imac kernel: ** Device in slot: SLOT--1 **
Oct 22 19:51:13 imac kernel: ** GPU Debug Info Start **
... etc until the shutdown.
It looks like this could have something to do with the issue. Unfortunately this is not something I can do anything with myself.
Yeah, you're right....not the same error....but I think it's similar. Stumbled across this thread:
People with that type of error.
It's definitely Graphics card related....wondering if iPhoto is taxing the card more now.
I have similar issues:
1) Using Definition and Remove Noise filters make iPhoto freezy and unresponsible. When iPhoto unfreezes, photo blanks with black and shows again only if I exit edit mode and enter it again.
2) When I use zoom in edit mode, I see multiple artifacts, color or black, on Navigator window, iPhoto freezes while I tries to move around clicking Navigator or moving display area on it by mouse pointer. After using Navigator for a long time (say, I edit dozen of photos using zooming on each), my screen, whole or part, fills up with randomly-colored noise and OS freezes completely.
