ASA 5510 question: ASA-713903 IP = x.x.x.x, Header invalid, missing SA payload! (next payload = 4)

my ASA 5510 works fine, all tunnels I built are fine. The x.x.x.x is not in my peer and I don't know who it is. When I check from real-time log viewer, it doesn't show source/destination IP/port, it keeps generating every 2~3 seconds and fills my log. what can I do to eliminate it? many thanks.

I've seen similar issues in the past with a former business partner still having our firewall configured as a VPN peer. My configs were long since cleaned up but theirs were not. I tracked down the company via whois (the VPN pre-dated my employment) but it was a big company that had been acquired by another big comapny and no one listed in ARIN responded to repeated e-mails.

I neded up blacklisting the source IP on my ISP-connected router and that made my firewall happier.

Hope this helps.
