It's a Pentium 133, 64Mb, Yes, although the problems with NFS in 2.1.x appear to be less severe than those that people have seen in -current. The bugs appear to mostly be race conditions when doing certain types of NFS operations (I can't be more specific), and bugs in certain types of error recovery. Many people have reported that they have never seen an NFS related problem even though they use NFS heavily. I think that most of the problems only occur when there is a high level of concurrency. -DG David Greenman Core-team/Principal Architect, The FreeBSD Project
