I checked the same under Mac OS X 10.6.8 (Snow Leopard). And I have

What version of Mac OS X have you?
Yup, Mountain Lion v10.8.4 :)
I suspect that xattrs with significant size is stored in compressed
state on HFS+. I implemented support of compressed xattrs partially but
I don't share this code yet. But, yes, EAs with size greater than 64 KB
can be a problem.
FYI, Example of output from one of the failing files. First from OS X and then same file after failed copy to XFS.
OS X Maverik:

Sorry, but I don't quite follow your thought. What do you show by this output? What do you mean? Could you describe in more details? Thanks, Vyacheslav Dubeyko.
Sorry late reply. The output is just to show what happen after I transfer a file from OS X to XFS that has EA bigger then 64k(I think). When I try for example to rsync this file from OS X to Linux XFS I get this error: rsync: rsync_xal_set: lsetxattr(""/srv/nas/home/apple_bak_rsync/xxxxxx/Pictures/iPhoto Library/Database/BigBlobs.apdb"","user.com.apple.FinderInfo") failed: Operation not permitted (1)
But also rsync can give this error. rsync: rsync_xal_set: lsetxattr(""/srv/danne/extern2/1000_EXT/2013/2013-03-05/IMG_6872-Edit.tif"","user.com.apple.ResourceFork") failed: Argument list too long (7)
Is this 2 errors related?
I will make a bug report for rsync also that it should not try to copy files with EA bigger then the destination can handle. But it would be great if XFS could handle this files and be fully compatible with OS X backups.
