You can start a new file and archive(*) the old one:

$ SET AUDIT/SERVER=NEW_FILE

This actually is in HELP, but (as was gently pointed out to me recently,
after I grumbled at someone else with a similar question) the organization
of HELP SET AUDIT is a little ... odd.

(*) Doing this regularly is probably a good idea.  Whether you choose to
"archive" to tape or to write-only memory (the DELETE command does this
very efficiently) depends a lot on your site's security requirements.
