For that problem, it can be true, the machine in speak has only 1 GB RAM (i386), although 8 disks. The freeze is a different beast, I've got it on 32-64 GB RAM machines (with NFS), and on 8 GB machines serving stuff with ftp/http/rsync/etc (no NFS). I'm not sure that the NFS and the non-NFS case is the same though. Thomas Burgess wrote: > > I think it depends on hardware and setup.
