Look down the list of threads..they should be listed, thread one: Logic , thread 2, uad-1 (or whatever plugins you have).. sorry for the long post but here goes:
Below is a partial crash log. I edited out the data for the first 5 threads to save space, but left the system, app, and crashed event, so you could see exactly what is going on.
You can clearly see that thread 6 crashed Logic, and that the plugin Predator was the bad guy in this case.
So, in this case I'd either look for an update of the problem app or plugin, or send the crash report to the developer, and hope for some kind of an answer on what to do.
So, there you go. Lesson 1 on how to see the problems when you get a crash report. It's not always this clear... Logic crashes all the time, all by itself, no clear reason why. But in this case, I can clearly see the problem, and then I can remove the problem plug-in, or at least I know what to be careful with when working, right?
