FCP crashes every 10 min = browser thumbnail icon is cause or effect

Question

I have been using FCP on a MacPro with 8gb of ram and a 2tb video raid. For the last several months, the program has been crashing VERY often (every 15 min). The crashing always occurs when I open a browser bin with video icons. As FCP brings up the thumbnails, it will get through a couple of dozen, then I get the spinning beach ball and then a crash. This has happened in bins with a dozen clips and bins with hundreds of clips. I usually can open several bins before this happens, but it ALWAYS happens.
I have tried the following:
reset PRAM
repaired permissions
trashed FCP prefs
trashed thumbnail cache
trashed FCP user data
changed thumbnail cache from raid to system drive, and back
tried adjusting thumbnail disk and ram cache settings
I was thinking maybe it was bad ram, but it seems to check out ok. I also have a AJA Kona3 card on the same system, but the problem seems to persist with or without the card installed.
Any suggestions would be appreciated. I do not have this problem if I switch to list view in the browser, but it is kind of hard to work that way when you are looking for a specific clip.

Answer 1

I found the AppleVADriver mentioned in the crash log. I then found out on discussions that the VAdriver is also causing problems with DVD player crashes and other QT related programs. I found a thread for DVDplayer where the guy had done the replacement of the driver from a clean version and it worked for him. So I crossed my fingers and did it on my system. After I did it, and re-ran permissions, there were a lot of VAdriver permissions that were updated to the newly installed version. The troubles with the VAdriver apparently go back about six months ago to an incremental 10.5 update.
So, after six months with FCP crashing dozens of times a day (not kidding), I have now been editing non-stop for two days on several projects with thousands of clips, and ZERO crashes.
