samba - Jun 1999 - Can't backup Samba share using NT Server across the network

We have a small site with about 100 clients running of a linux box and
samba (which, benchmarks notwithstanding , seems faster than when it
used to run NT) .

We have been backing part of its disk space up using a NT server. We
moved from 2.03 to 2.04b and the backups started failing. The error in
the error log is as follows


[1999/06/22 17:58:42, 0] smbd/files.c:file_new(85)
  ERROR! Out of file structures
[1999/06/22 17:58:43, 0] smbd/files.c:file_new(85)
  ERROR! Out of file structures

I looked around and found a patch for nttrans.c that fixed this error,
but the backup still fails.

We can view the share from the machine, we can open the files from the
machine. We just cant use ntbackup from the machine. It gives the
following errors

Backed up 1 files in 0 directories.
Processed 307,620 bytes in  24 seconds.

Needless to say that they do have permission. No files get backed up at
all.
In fact the tape is completely empty!

I am working around this so the problem is not critical for me

Best of luck
