>Description:
in FreeBSD 7.x, -n 12 would spawn 12 server proceses.  Since going to 8, it always just one:

  832  ??  Is     0:00.06 nfsd: master (nfsd)
  833  ??  S    1451:56.62 nfsd: server (nfsd)

number of threads shown in top is always 4.  I have tried -n in nfs_server_flags in rc.conf.  I have also tried stopping nfsd and trying to start it with  nfsd -n 12, same effect.

Is this now normal behavior for NFSD? 
>How-To-Repeat:
Run FreeBSD-8 and try nfsd -n{some number other than 1}
>Fix:
unknown
