Hmm, I'll see if I can replicate this. So, the two clients were writing two different 2.7GB files or they were overwriting the same file? If it were two different files, I guess the filesystem would eventually fill up :) Also, what architecture machine was the server (IA32, IA64, PPC64 ?) and how many nfsd threads were you running?
