What do 'cat /proc/sys/fs/file-nr' and 'cat /proc/sys/fs/file-max' give
you?
Also adding up the number of files qmail qmail opens will give you an
under estimate. Qmail is not the only thing running on the machine and file
descripters are opened for other reasons than just explicit file access by
an application.
Try doing 'echo 8192 >/proc/sys/fs/file-max' as root then a
'cat /proc/sys/fs/file-nr' after some time.
The 3 numbers from file-nr are maximum used, currently in use and maximum
available.
