UNIX process question

Have a question about what is nfsd and should there be a lot of those commands on the system?

We have a script that looks at IDLE CPU under 60% that we wrote. Here is the out put . I am just curious.

The nfsd is the NFS daemons that run on an NFS server.

By default, 16 of them start up.

You can find information on how to limit them in the /etc/rc.config.d/nfsconf file.

Best regards,

nfsd commonly spawns 16 daemons in a default configuration. They will just sit and sleep until there is need for them.

Nothing to worry about.

If you do not use NFS, you can turn off all the extra daemons (both nfsd and biod if you have both seerver and client enabled). SAM will do this easily, or you can stop the 3 components, then edit the nfsconf file to turn off all NFS. To stop the processes:

/sbin/init.d/nfs.client stop
/sbin/init.d/nfs.server stop
/sbin/init.d/nfs.core stop

And edit /etc/rc.config.d/nfsconf to set client and server =0, turn off automount options and also turn off START_MOUNTD.
