Strange PIX behavior

Hi, I recently saw a strange behavior on my PIX v 6.2.(4).

We get hundreds of the following message in the space of a few seconds:

%PIX-6-106015: Deny TCP (no connection) from /25 to /4739 flags ACK on interface inside

The problem totally swamped our internet connection, and rebooting our mail server did not help. Finally we rebooted the PIX and it went fine and never happened since.

Has anyone seen this behavior? I'm wondering if there is a known PIX bug associated with this?
