When I issue the ps ax command I see that nsfiod 0, 1, 2 ,4 is running. This did not happen under 4.x systems. I also get this message in the boot log "Mounting NFS file systems". Only way to stop the auto spanning of these un-wanted and not needed tasks is to recompile the kernel source with all nfs options commented out. Any un-used running tasks is a potential security risk. This was reported 1/16/2004 in 5.2 RC2 as Problem Report kern/61438 and somebody lowered its importance so it has never been addressed. Why have a ‘RC’ version if problems are not going to be addressed and fixed before becoming a release version. >How-To-Repeat: install 5.3 from scratch and answer no the both NFS sysinstall questions and then after install is completed issue ps ax command to see the 4 mfsiod tasks running >Fix: recompile the default kernal without nfs support and incorperate it into the 5.4 release or find and correct what ever was changed between 4.10 and 5.3 so those nfsiod tasks are not auto spanned at boot time unless nfs client or nfs server enable statements are in rc.conf. >Release-Note: >Audit-Trail: >Unformatted:
