Big error fails every time!

[skumancer]

I have an Xserve G5 with a LaCIE 250GB external hard drive hooked up via Firewire 800.

Every time I try to backup to a sparce image inside the Xserve, I get an error after 63 thousand files.

The error is the following:

"| 08:08:06 PM | Error | SDCopy(16968) malloc: ***error for object 0x335570: double free"

I don't know what to do. I've deleted the image and recreated the image, moved it from destination and it still is not working.

This is almost always due to a problem with ACLs on the source volume. Please check them to see if they're properly constructed -- a common problem I've seen is applying inherited ACLs recursively to a tree of files. It's wrong to do, confuses the ACL copying routine that we call (Apple's actually), and can cause this exact kind of error...

Any idea how to correct it?

I don't use ACLs on this volume. At least I don't remember I do.

If you're not using ACLs, you can turn them off with fsaclctl. Check "man fsaclctl" for a detailed discussion of the command. In general, you'd use:

fsaclctl -p / -d

to disable ACLs, assuming you're backing up the volume mounted at /.

Done!

Thanks a lot, that made it work!

Great -- ACLs seem a little fragile, still, in Tiger...
