> Configuration:
> Sparc 10, SunOS 4.1.4, no patches
> Problem:
> This machine is heavily used for number crunching, development,
> and CAP service. In the evening, when the system dump processes
> are kicked off, it hangs. Messages in /var/adm show many
> "NFS getattr failed" messages to the two NFS servers it is hitting
> heaviest for its number crunching duties. Back on the tape host
> where the remote dump processes are initiated, the remote dump
> process for this host is hung.

patch. Thanks for the replies from the list!
