/usr/etc/kvar on decs will change the value of any kernel variable.
The variable that increase the number of open file a single user can
have is "max_nofile". To read the current value that it is set to, as
root, run:
kvar -k -s max_nofile -rl vmunix
(I believe the default is 0x40)
To set it to a higher value, like 0x100, run
kvar -k -s max_nofile -v 0x100 -wl vmunix
to change the value in the in-memory kernel, and
kvar -k -s max_nofile -v 0x100 /vmunix".
to change the on-disk kernel. man kvar for more details.
