LR2 crashed three times yesterday and I'm wondering if it is time to purge my cache.
I have already selected "Relaunch and Optimize" under the Catalog preferences. No help. Would it help of I didn't choose full-size Previews? Would it help if I deselected "Automatically write changes to XMP"?
Hi Henry. The first thing I would do is to right click on the app, select Get Info, and choose 64-bit mode for LR2 (Note: I'm still running 10.4, and it doesn't have this option, so what I'm describing is what others with 10.5 have told me). This will let it use as much ram as it can get. If you don't have 64-bit mode selected, LR2 is limited to using 4GB of ram or less.
The second thing I would try is turning of the automatic writes to XMP. The cache, as far as I know, stores the image previews. I don't think purging it would help, tho obviously I don't know for sure. I believe purging the cache will force all the previews to be regenerated, which is time consuming on LR2. But hey, desperate times call for desperate measures, so at this point I would try everything and see if it has a postive effect.
Another thing I would do is check whether previews are being generated while you're trying to do something else. Look for a Previews progress bar in the upper left corner of the screen. Generating previews seems to take a lot of resources, and totally brings the app to a halt on my machine until it finishes the previews. I just go make myself a cup of tea and come back when preview generation is complete.
Finally, I would try shutting down other apps that might be consuming a lot of RAM.
So far, I'm very disappointed with LR2 performance. I love the new local adjustment tools, but the thruput issues with LR2 really leave a bad taste overall.
