I'm getting this from one of my PIX 501's. The other 3 are functioning fine. I have a VPN Concentrator 3005 at my corporate office and then the branch offices have PIX501's that connect via IPSec to the Concentrator. In the early stages of trouble shooting, I did persistent pings to the inside int and to the outside int. What is happening is the inside will time out for a single packet. During this, I see in my concentrator the the Tunnel is droppped. I started ISAKMP debugging and this is what I'm getting. Any help would be much appreciated.
