Site to Site VPN with VPN Concentrators

I'm setting up a site to site, and have followed the instructions from the Cisco site. Phase I completes, and the other concentrator connects. Then Phase II repeats itself about 10 times and then disconnects. Each time the entire process lasts 24 seconds. Anyone have any ideas? Here is a copy of the log from the local concentrator:

This one lasted longer than normal because I had a constant ping initiated on my side to a host on the remote side. Thanks in advance for any insight.

Re: Site to Site VPN with VPN Concentrators

QM FSM stands for Quick Mode Finite State Machine. The encryption process consists of as a number of "finite state machines" where each FSM accepts input from the previous FSM. The error encountered could be due to a number of reasons and the error message by itself doesn't shed much light on the likely cause. I would suggest rechecking your configuration and looking out for bugs associated with your software.
