A little help please,

I have a production system where the /var/adm/wtmp file has grown huge,
about 264M, and is filling up /var. I've read the online docs about using
fwtmp to make an ascii file, editing it, and converting it back. Also read
about wftpfix command and nulladm. Being somewhat cowardly about trying new
stuff on production system, I'd like some advice.

What would be a reasonable course to take? Do I need the history contained
in the wtmp file or can I create an empty file (nulladm wtmp) without major
issues? If I have to edit the ascii version of the file, what do I edit out
or leave in? Any known gotchas?

I know the questions are pretty broad, but I would appreciate any guidance.

TIA
Harold
