Patient: "Doctor, it hurts when I type ``nmap -sP 172.22.0.0/16''!!"

Doctor:  "Don't type that."

Patient: "Oh, ok..."


The system will panic with an 'out of mbufs' message when I run the above
nmap command ("ping scan" a class B subnet - my internal IP network).

Should this be happening when run as a normal user??  The kernel is pretty
stock with maxusers 32, no NMBCLUSTERS option, unneeded devices removed.  
There is 64M RAM and 256M swap; it is has dual 90MHz P54C's.

This system (my workstation) is a:
FreeBSD 3.3-STABLE #0: Mon Sep 20 09:44:35 EST 1999

I am:
bash-2.03$ id
uid=1000(andyf) gid=1000(andyf) groups=1000(andyf), 0(wheel)

I have:
bash-2.03$ limits
Resource limits (current):
  cputime          infinity secs
  filesize          1048576 kb
  datasize            65536 kb
  stacksize            8192 kb
  coredumpsize       131072 kb
  memoryuse           65536 kb
  memorylocked         8192 kb
  maxprocesses          256
  openfiles             256

I use:
bash-2.03$ 


How would you go about preventing this problem?

Thanks.
