no free inodes

[db]

Hi all

I have a webserver (FreeBSD 5.3 on a i386 with 512 mb ram) serving over 6000 
users pr day, but when I try to run proftpd i get:
/var: create/symlink failed, no inodes free
foo.domain.topdomain - error opening scoreboard: No space left on device

web1# df -h

I've google and read "man tuning", but I'm still unsure how to fix this. Do I 
need to reformat /var or can I fix it with sysctl?

Are there other things I should be aware of?
