Our sun 4/280 file server has a similar problem.  The other day, the
number of jobs went thru the roof and the nfsd's (eight of them) were all
taking about 5 to 7% of the cpu time.

We ignored it for the day, hoping it would mellow out because we had two
jobs that had been running for days on the machine and couldn't really
just bag them and reboot.

I hope someone will come up with the solution to this problem.
