I have an NFS exported directory "/share" which contains "/share/Mac"; the "Mac" directory is itself exported vi netatalk, and contains several GB of Macintosh files.

If I execute

tar cf /dev/null Mac when "/share" is my current directory on the 4.10 box nothing happens, other than consuming a lot of machine cycles.

On a 5.3-STABLE box, where the /share directory is NFS-mounted, when I execute

tar cvf /dev/null Mac

when /share is my current directory I get

p4dc6# tar cf /dev/null Mac
archive_write_pax_header: 'x' header failed?!  This can't happen.
p4dc6#

This is reproducible, and happens after a specific file in an Apple network software installation directory.

There is nothing in /var/log/messages.

A Google search found only a reference to one message in the "perforce"
FreeBSD mailing list (change 66084) which appears to show that this error message was added on 11/30/2004.


dmesg header is (there are two physical CPUs, the kernel is SMP):

I can provide additional information, assuming that this is something as yet uncorrected.
