I've got a problem installing SP4 - copying fails with a 'Vol SYS is out of space' error, problem is ,
there is plenty of space (1.5GB as reported by iManager) - I remember this happened with SP3 as
well but of course I can't remember what I did to install it.

Same SP4 installed on a newer box without error.

Problem box is NW6.5 SP3 Vol1 is NSS but SYS is Traditional volume - I've purged SYS also but still
no go
