Can NFS server not responding trash vi?

[Ssi]

 I have a Sun 3/160 serving 5 diskless clients.
We get a fair share of `NFS server not responding..'
messages. Sometimes when a user writes a large file
(250000 bytes) from `vi' the file gets trashed.
This seems to happen when the write encounters an
NFS error. The last time this happened there where
several `spurious level 4 interrupt' errors on the server
console, I don't recall seeing these on the other
occasions.
 I'm running SunOS 3.5
