Do you not want to rotate because of the time it takes?
Yep, the keep_logs does a rotate without a limit.

The max_log_file value is an unsigned long so it should take a very
large number. However, in case there is a lot of auditing you are not
prepared for, I'd suggest limiting the file size to 2GB. The rotate time
should be similar regardless of the file size.

BTW, in what a time period are you getting the 3-4GB amounts? Are you
happy with the data you are getting - or maybe you could pare it down
some with audit.rules tweaks on the senders?
