nfsiod now runs as a kernel process and is control by these sysctls: vfs.nfs.iodmaxidle: 120 vfs.nfs.iodmin: 4 vfs.nfs.iodmax: 20 It looks like setting vfs.nfs.iodmin=0 and then klling them off works. We probably should think about changing the default to 0 and setting appropriate values via /etc/rc.d/nfs. Over all, I can't say this is a very high priority though patches would certaintly be accepted. -- Brooks -- Any statement of the form "X is the one, true Y" is FALSE.
