Depends on what you query. Filesystem statistics shouldn't be a problem
File sizes on the other hand. It's probably better to fail stat() calls for
large files. lseek() would also need to handle large files, but I don't know
how the NFS server could influence it. I guess you can only fail read() and
write() when you pass the 32bit limit.
