I have deleted audit.log and after that I generated events but audit.log file is not getting created immediately

I went to ~/Library/Application Support/couchbase/var/lib/couchbase/logs directory and removed audit.log

Then I created users, issued N1QL statements and waited for more than hour but still audit.log file did not get created

I don't know the correct behavior hence logging it. My expectation is that it will generate immediately
