So you just installed that new Xserve and you are starting to notice that the AppleFileServer is spiking when your users are searching the AFP volume for some media. To fix, first, backup /etc/rc.server (just in case).
Then change this line:
sysctl -w kern.maxnbuf=90000
Replace the 9 with a 2 and then save the file and then reboot.
