I just posted this under a related heading in Architalk. My "disk is full" message problem sounds similar:
I'm having "issues" with my new G5.
Wonder if anyone else shares my newfound concerns with Apple for releasing 10.4 too early.
This G5 worked great for two weeks. Fast renderings etc. with 5GB RAM, though not as snap/snap as I'd thought it might be as compared to my old G4. I love the 256MB video RAM compared to just 64MB on two monitors before.
Anyway, seems the entire Hard Drive filled up in the first two weeks, ...all 250GB of it. Since I've not been reborn a speed demon, I was pretty sure something bad was happening. Then the poor machine got too full even to boot.
I've clean-reinstalled just the Tiger, no Apps yet. But may go back to Panther as my Apps were doing just fine with it. (I'm using our trusty G4 for this note.)
We'd been using the G4 as an office server linking a Dell PC to my G5 through it, and setting the G4 to backup to an Iomega external drive every four hours using the Iomega software. It feels as if the backup might have gone into the G5 instead though, somehow, at the rate of 40GB every day.
Ideas anyone? Common problem with Tiger, 10.4.1 perhaps?
