Samba &| VFS

[Rob Hudson <rob@eugene.net>]

We recently set up a Samba server on Debian potato.  After a little
uptime (about 30 minutes to an hour) we saw an error message that
said: 

  VFS: file-max limit 4096 reached  

I did some searching on the net, and found what might be a solution.
I added a simple .sh script to the startup that increased the file-max
and inode-max via the following:

  echo 16384 > /proc/sys/fs/file-max
  echo 65536 > /proc/sys/fs/inode-max

That seemed to help a little.  Now we are getting errors that say
something like 'no fork() resources available' or something like that.

Upon boot, I see this message:

  VFS: Mounted root (ext2 filesystem) readonly.

even though I'm able to write to the root filesystem.

I don't know what other clues I can leave.  Thanks for any help on
this.  I'm not sure if it is a Samba issue or a kernel issue or a
filesystem issue.  All the server is running is ssh, apache, samba,
and the other basic services (cron, inetd, etc).

Thanks.
