If an NFS client unlinks a file that it has open, it will be silly_renamed, and if the client then goes silent, it might never be removed. So we already theoretically have a possibilty of ENOSPC due to silent clients. Have we heard of this becoming a problem? Is there reason to think that the Courteous server changes will make this problem more likely? NeilBrown
