Running out of something

[David DeLauro]

Hello,

I've been having some problems with the samba Version 2.0.7.  I have
about 800 users that can connect to this server and these users are
mapping 2 shares from this machine when they connect.  Well, when the
load gets up around 450 or so users the machine starts to give samba
errors such as:

[2000/11/09 20:07:47, 0] lib/util_sock.c:write_socket_data(540)
  write_socket_data: write failure. Error = Broken pipe
[2000/11/09 20:13:47, 0] lib/util_sock.c:write_socket_data(540)
  write_socket_data: write failure. Error = Broken pipe

and if I try to do simple things like "ls" I get the following error.
ls: fork: Resource temporarily unavailable

I'm running slackware 7.1 and when I look at /proc/meminfo I have plenty
of free memory (swap and ram) and if I do a cat on some of the files in
/proc/sys/fs  I get the following:

minauros /proc/sys/fs # cat file-max 
32767
minauros /proc/sys/fs # cat file-nr 
3530    1766    32767
minauros /proc/sys/fs # cat inode-nr 
65540   8590

So it looks like I have plenty of file-handles...

Can anyone help with what might be wrong and if so what might be the
solution, it would be greatly appreciated...
