That could have been connection unreliability. There's an unresolved NFS bug that will hang the IRIX system for an extended period of time if the NFS connection is interrupted by some manner.

This is definitely a frustrating issue.

But yes, SGIArtist you really really need to ensure your configuration supports NFSv3 and has the daemons I mentioned running. That's probably your first step. Anything beyond that is ancillary.

It's possible to get NFS for IRIX even on Windows server 2008R2! (using the Unix stuff that Windows has done in the past, forget it's name) but each implemention has its own finnickyness with legacy (pre-v4) connections because v4 was AFAIK an entire protocol rewrite! It's like comparing Japanese to Chinese!
