NFS Emergency - RPC and NFSD online but no connection??

[Kaya Saman]

Actually a bit more scanning shows Darkice is using 100% of the CPU for 
some reason?

I've commented it out in /etc/rc.conf and initiated a restart so I hope 
that, the lower load average will make the system start accepting 
connections again which is a plausible cause for my issue.

After testing I will have more information to share, hopefully it will work.

If that's the case I will look at limiting CPU horsepower per 
application so that my lowly system has some room left to compute other 
things too.
