mv fails with "Too many open files" when moving _many_ files

[Cyril Bouthors]

Hi,

I'm having problems when moving everything from a directory that
contains 10852 top level directories and a total of ~300000+ files and
subdirectories with this command:

# mv * ../../../webalizer-clients/

It fails with:

mv: cannot create regular file 
`../../../webalizer-clients/bouthors/usage_200305.html': Too many open files
mv: cannot create regular file `../../../webalizer-clients/bouthors/.htaccess': 
Too many open files
mv: cannot create regular file 
`../../../webalizer-clients/bouthors/index.html': Too many open files
(...)

The same command runs successfuly with ulimit -n 1048576 but you can
see that many (useless?) file descriptors are in use:

# ls -l /proc/`pidof mv`/fd | wc -l
5643
# ls -l /proc/`pidof mv`/fd
total 5533

I think this is a bug, I'm using "mv (coreutils) 5.2.1" with Linux
2.6.6.
