I'm getting a lot of severity 1 - attack in progress on my ASA 5505:
Deny TCP reverse path check from xx.xx.xx.xx (external ip) to outside interface

I'm new to these logs; severity 1 seems serious.
Are these common? should I be concerned or is the asa just doing its job and telling me about it?

Any suggestions or input would be appreciated.
