df output looks fine.
Sounds like a permission problem, are you sure you have executed the chown step?
to check, run “ls -lad /Database/var/register/system/havp/tmp” from the shell. You should see (only the text in bold is important, the remaining text may differ a bit when you run):
drwxrwxrwt 2 havp havp 540 Feb 5 15:32 /Database/var/register/system/havp/tmp
