Your trying to run too many memory hungry applications at same time.
Tweaking the kernel is not going to help you. Adding more ram will.
Better to only run single network monitoring application at a time.

Subject: No Buffer Space Available
Please forgive me for being quite new to FreeBSD...
I noticed while I'm trying to monitor my network from my laptop
running fragrouter -B1 and trying to monitor the connections coming
and going from another machine on the same network through ettercap
ethereal that I get a lot of No buffer space available messages as
SEND L3 ERROR: 1500 byte packet (0800:06) destined to 192.168.1.4
not forwarded (libnet_write_raw_ipv4(): -1 bytes written (No buffer
I even was not able to nmap the other machine.
I was trying to run these test over my iwi0 card and I'm on FreeBSD
While googling I found several posts about setting certain kernel
parameters with sysctl and stuff can help but I didn't really get
clear picture of the problem and how it can be resolved, if it is
considered a problem. Or is it the iwi0 doesn't handle much load?
Thanks in advance for any input
