Logic crashes repetitively when working with video


Recommended Posts

Unfortunately the opportunity to say 'hi' on this forum goes along with the serious problem I have to ask you to help me with. I have only a week to finish my project so please do!



I started my work importing video and two audio tracks and addingo some markers. I got back to it couple of hours later and my problem appeared.


After max. 3-4 minutes of work logic quits giving me an error report like this (there's a lot more should I paste it?):

It seems to happen when I few times perform an action such as changing a screenset, closing another open project (empty), etc. I think the cause is opened video preview floating window (on the second screen).


I woner if it may happen because of little disk space left (2,4 GB) but the video isn't big - 90MB. It's obvious I really need a preview so what can I do to stop it from happening?


My set is:

macbook pro 2.53ghz

4gb 667

geforce 8600gt

apogee duet


OS 10.5.8

logic 8.0.2

Yes, it could, and whether or not that's the culprit, it's a bad idea to run your system like that. Mac OS X needs much more available space than that on your hard drive so it can page RAM in and out of the disk.


For Pro Applications it is typical to recommend 10 to 30% of free space on the system drive. I personally would try to keep it closer to 30 than 10.


Meanwhile, another thing you can try is to quit Logic, remove the preferences ~/Library/Preferences/com.apple.logic.pro.plist (move them to the desktop for example) and reopen Logic.


If that solves the problem you'll have to reprogram your preferences manually, if that doesn't you can quit Logic, move the pref file to its original location and reopen Logic.


It would help if you can paste thread(0) (the thread that crashed).

Thank you for your quick response! It's great to see a forum like this one :-).


I always try to keep enough space free, temporarily I have a little emergency with external storage. This is first time this problem occured so it may be it. I'll try to get an additional HD asap.




In any case I paste the Thred:

I ensured there are 30GB free disk space left, I switched off all external devices and the problem still appears!


It is sufficient to start Logic and change the screenset 4-5 times and it crashes. Anyone, pls help!

Logic 8 is crumbling... I had thought it was the 10.6.6 update, but seeing as you're not on Snow Leopard :?


I couldn't find out what caused it, but here's a thread detailing what I did, hopefully something in there might work for you:




Here's a good general troubleshooting guide: http://www.gballard.net/macrant/osx_troubleshooting.html
