What are you swapping >on? Are you using NFS for either swap or your binaries? Swap is local, while all binaries and home dirs are mounted over NFS from an Irix 6.2 server. I've seen this error from a 2.1.5 server as well though. Our network is fast and very rarely saturated, so I do not believe that it would actually lose contact with the server unless its a server problem. However the same thing works from our SGI cluster, so I would not think that the case. We will be installing patches this friday, one of which i think is NFS related, so I will check that again though. > >> Chris Csanady > >-- >]] Mike Smith, Software Engineer msmith@gsoft.com.au [[ >]] Genesis Software genesis@gsoft.com.au [[ >]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ >]] realtime instrument control.
