Hi all

I have a client working on a feature-length project with a large amount of media and attached drives (11 Firewire drives connected to a PowerMac G4 on 10.4.11, using FW800 PCI expansion cards). The system is pretty overloaded in terms of RAM, CPU capability and I/O, but at the moment they don't have the ability to do any upgrades.

One of their issues is frequent crashing of Xpress Pro, especially when consolidating media between drives or playing back a sequence. Their application is 5.8.4 and Quicktime version is 7.1.6. They also have a Mojo directly attached to the Firewire bus.

There's nothing obvious in the Avid log that speaks to me; I enclose the last few crash items in case anyone has the time and inclination to look at them and might have any insight. In every case, the crash log begins

Exception:  EXC_BAD_ACCESS (0x0001)

Codes:      KERN_PROTECTION_FAILURE (0x0002) at 0x00000000

Would it be a sensible troubleshooting step to delete precomputes, perhaps?

Grateful for any advice - Thanks!

Matt

Less is more.  Sounds like there is too much of something that's gumming up the works.  Could be bad media.  Could be a bad firewire drive on the bus.  Could be too many media files in a folder.  Could be too many objects taking up memory.  See if you can minimize things for a test to see if the problem can be eliminated if there is less of everything.
