I have the following on a machine: ps aux|head -n 1|ps auxw |grep nfs root 317 0.0 0.0 0 8 ?? DL 12:47PM 0:00.41 [nfsiod 0] root 318 0.0 0.0 0 8 ??

IL 1:51PM 0:00.00 [nfsiod 19] It seems that for the most part most of those nfs clients are not used. I then wonder why they were started. What would be the impact on setting the upper limit of clients to 10? Specially on a case like the above it doesn't seem like 20 were needed to begin with.. Also, on the server how does one change the number of running server daemons? Only way I found was to kill all nfsd daemons and start it with the new number of clients.. there must be a better way (I sure hope so).
