Ah, I misinterpreted what you meant. Are there other processed besides the
copy of three large files tat might be keeping lots of files open? Have you
checked the file allocation limits in proc (/proc/sys/fs/file-nr)? I hear
for 2.6 kernels you rarely have to tweak these settings, but it might be
worth looking into if you haven't already.
