%PIX-4-419002: Duplicate TCP SYN ?!?!?!?!?!

Posts: n/a
I'm getting the following messages 7 times a minute from 2 inside addresses
to the same destination host.

%PIX-4-419002: Duplicate TCP SYN from inside-HBG: to
outside-HBG: with different initial sequence number

The destination host network is a DSL Network on the back side a a Cisco
1700 series VPNd into a PIX. That particular host does not exist.

I've checked the PC and it is sending the packets but i dont know
what process is doing it.
