--- Comment #21 from Peter Eriksson <peter.x.eriksson at liu.se> ---
Just a quick feedback/comment: We've now been running our production servers
with a patched kernel as per above since Monday night and so far everything
seems to be running correctly... No kernel panics so far - *Fingers Crossed*
:-)


Just a quick wish for someone - would it be possible to have the CLIENT_MAX and
the hash table size increased a bit (like to 512/1024) in an "official" kernel
patch for 11.2? 128/256 are very low numbers - especially since every client
principal (HOST$@REALM) also uses up a slot in that table when a client
connects... 

So basically it just requires 64 clients (with a different user on each client)
to run into the CLIENT_MAX limit (which I'm guessing will cause gssd extra work
so it's not a showstopper, just annoying :-).

(There are a bit too many kernel-crashing problems reported with ZFS in 12.0
for us to upgrade there yet).

I know I can build my own kernel with those limits increased but it would be
nice to not have to do that (and distribute it to all our servers) whenever a
new kernel/security patch arrives... :-)
