FCP locking up while capturing to RAID
Hi guys,
FCP 5.1.4 is locking up during capture at random times. I’m capturing SD material to Uncompressed 8-bit NTSC D1 on a RAID. This system has been heavily used for capturing/rendering over the past 10 months with no problems until recently.
I’ve deleted prefs, fixed permissions, booted from a new user account, reinstalled FCP, done about everything I can think of relating to software before I reinstall Tiger.
I was wondering if anyone had any ideas as to the cause. Could it be the RAM?
specs:
Mac Pro 2.66
Mac OS X 10.4.11
QuickTime 7.3
FCP 5.1.4
4 GB RAM
AJA Kona LH
Fibre Channel card ->
Xserve RAID – 1.8 TB HFS+ format (350 GB free)Thanks a lot

Have you run the Kona System Test on your RAID? What kind of read/write speeds are you seeing?
How about Apple’s RAID Utility? Any problems with the RAID itself?
It looks like your RAID is pretty full too (350 GB free), any way you can free up some more space?

Yes i ran the test and i was getting ~85 MB/sec write for 4.0 GB file size.
I’m reading also that QT 7.3 is causing problems for some users, I might try downgrading to that and see how it goes.
Hmm. For some reason the RAID Utility is now acting up. Not a good sign…
Thanks for your help Matt!

I could definitely see how the newest version of QT could cause a problem with an older version of FCP. Any chance you cloned your boot drive before you upgraded? If you did, try booting from that and see if you still have problems capturing. If you do, it’s not Quicktime causing the problem. If you can capture fine from your old system odds are the problem lies in your updates.

I ran into this problem last year when I would randomly have my entire system freeze up while accessing files on the RAID. Wanna know the solution? YMMV, but it’s worked for the four others I know that have run into this:
IN System preferences, go to Energy Saver and uncheck “Put the hard disks to sleep whenever possible” On the RAID we use, for whatever reason, the OS was saying “Nah, nothing going on here and telling every “local” disk to sleep. Then we’d fire up FCP, try to access something on the drive, and the RAID would seem to be working, but it wasn’t. FCP would freeze, system wouldn’t work, wailing, gnashing, etc.
Hope it works for you, too!
