Ben, I'll be glad to try 12.1 - it sounds like a great move to have
the blocksize adjust based on the file size. However, we weren't
seeing the long times you did - Our failures were occuring after
around 15 minutes. I don't know what the difference is, but it's just
a little more information for you. It could be I/O system
differences, I'm running this on a dual Athlon 2000+ with a 14 disk
ide-to-scsi raid, with 512MB cache. It's possible that the large
cache is really coming into effect here.
I'll try 12.1 today and let you know if it works.
Thanks again,
-Ty!
