Did you remove the rule that caused the massive amount of logging?

Auditd will drain that buffer.  The default is a queue of 64 messages,
which should drain reasonably quickly if the rule has been removed and
the queue length hasn't been overridden to a huge value.  Otherwise,
there is no other way to drain that buffer.
