8 core crashing at end of any and all renders

This is getting crazy. I've tried every conceivable setting and nothing works. At the end of any render with this machine I get a crash with the little tag saying that it auto saved. I then have to force quit and restart. Makes one very good at saving. Other than that there are few problems.
Anybody have any ideas. There is lots of chatter out there about this kind of problem but this seems to be unique to the 8 core. The other machines (two quads) are stable and behaving, if somewhat slower.

it would help to know a little about your system (os version, ram) and what version of ae. also, just to be sure, you aren't running quicktime 7.4.0... there were a lot of problems with that version of quicktime.
you could try moving the folder that contains the ae pref file to the desktop. then open ae and render any previous comp to see if ae crashes. this will at least rule out any corrupt pref or bad settings.

I had a similar issue not too long ago. I'm on an 8 core power mac. Every time my machine would crash on the very last frame of my renders. A temporary solution for me was to turn off multiprocessing. This helped me complete my renders until our engineers were able to fix the problem (it turned out to be a network issue with my account). This was my situation...it may or may not help you. But like kevin said, check your version of quicktime and move your prefs file to rule out any bad settings.

[Benjamin Thompson]"it turned out to be a network issue with my account"
interesting.. i was a little suspicious of a permissions problem, which sounds similar to what you were experiencing. almost more interesting is that turning off multiprocessing helped with a network/account issue.

Let me try disabling the network and see if it crashes. Pretty soon I'll have to put a pyramid over the studio and start the chanting again. Computers can't live with them and ....

Thanks for getting back. I've turned on and off everything and in various versions. The weird part is that it finishes the render and then crashes saving a _1 version of the file. This file could be 1 sec long or 3 minutes long, it doesn't matter. It smells like a incompatibility between all the elements (computer, system, and AE) but I can't figure it out.

Are you using any interframe-compressed footage in your comps? Any flavor of MPEG, H.264, m2t, etc? If so, convert them to a codec that doesn't use interframe compression.
You should also watch out when you import Photoshop documents with layer styles. AE is not friendly to all of them.

I figured it out, although I doubt that Adobe will cop to it. My audio interface is an old MOTU box called an 828. New drivers, etc. (Audio in AE by the way is set to internal speakers.) Leave the Motu box plugged in, crash. Unplug the fire wire, or turn off the box and no crash. I haven't checked with Adobe but I will bet that the screams of denial will be loud. If I can get them to even say hello.
Meanwhile the MOTU box works with everything else just fine, and since we do a fair amount of audio post it's important. Works with FCP, works with Logic and Soundtrack, works with the computer sounds, etc etc.
It's probably in the "media core" whatever that little hidden bundle really is.
MOTU claims they have never heard of this. And my five will get you ten that Adobe is to blame, somehow. So now the fix is to turn off the 828 when I render. Not too painful but really silly. Somewhere out there some poor schmoe like me is going to have to unplug every totally "unrelated" device to discover this. Maybe they can find this post and avoid the pain.
"One step forward....."
Thanks to everybody for taking a stab at this.

Weird is as weird does. I tried other settings, and I hardly ever render with audio. I usually just have the audio there for reference. AE really does audio badly. You would think after all this time, but noooo.
As to the crashes, this just reeks of the media core thing. Apple supports it badly and with the new computer and Leopard it just seems that there is something not right. We even have trouble playing h264 files with that new leopard interface, which is cool when it works (ie spacebar from the finder). But our 3d stuff just flies, and for the most part AE behaves. It's just stuff like this that pops up and, against all logic, refuses to work correctly.
I sent Adobe a note but I haven't been impressed with their response to stuff like this. I'm kind of wondering why other users of MOTU interfaces haven't had this problem since according to them it's the same set of drivers for most of their stuff.

interesting...i'm using CS3 with QT 7.4.5 on a Quad G5 and 10.4.11 - and i'm seeing a very similar problem. I can render and length of sequence, but AE hangs on the final frame and needs to be Force Quit.
I am trying to render out a small 2 sec logo which is made up purely from photoshop layers, no audio at all. I'm rendering it as lossless with alpha at 25fps sd pal resolution.
The weird thing is that whilst i don't have a Motu 828 connected ( i do have Digidesign 002R and Motu Digital Timepiece), and i'm not using audio on this sequence. When i checked Activity Monitor after the last freeze, one of the process that was not responding was the CoreAudio !!
Time for some more tests i think....

I'm not sure that this is a direct connection but.... When I boot the activity monitor I see that the core audio is in red and "not responding". Since the core audio is, I believe, unique to Pro Tools and since they only yesterday started to support Leopard maybe the problem is somewhere in there. I've never been very impressed with PT's support of Apple audio.
In the meantime, the only solution for me seems to be to turn off my MOTU box to solve the rendering problem. Seems crazy but after talking to all the players and listening to their denials it seems that it will be a while before this gets resolved.

Sorry to bring this back, but I've been having this issue also. Tried trashing the prefs, tried, changing some settings around in the preferences, all to no luck...
until now....
Good thing I saw this thread because my issue was fixed also by turning off my MOTU Ultralite for rendering. I am in complete agreement with you Tony. The only issues I've ever had with the sound device is that sometimes it'll go haywire when my Time Machine starts to back up to the firewire drive. Other than that, no issues.
Looks like I'll be turning off my sound device when I render. What a crappy solution lol. Anyone having it working with other external sound devices?
