The size of the gnode (generic inode) table depends on a number of system
constants, the easiest to fix is MAXUSERS. Go into /usr/sys/conf/YOUR_SYSTEM,
and increase 'MAXUSERS' to something larger than what you've got. Config,
make clean, and make. Voila... more gnodes!

Note that this does *not* violate your license. You can do whatever you want
with MAXUSERS - the license restriction doesn't use it.

We run a Microvax 3600 with a 2-user license here with MAXUSERS set to 32.
32 is about the minimum for a timesharing system or a system that does
any real work (we have 10 vaxes here... all are set to at least 32).

FYI, gnodes are an in-core abstraction of the inode. They are used to
reference files in both normally mounted file systems and NFS mounted
file systems. 4.3 BSD has the same idea, but they're called 'vnodes'.

Hope this helps.... (I'm sending by mail also to make sure you get this).
