I'll be more blunt with my advice.
1. Find out if the servers are seeing ICMP 3/4 packets when the router fails
to fragment the packets. Run a sniffer on one of the servers, or something.
2. If they are, it's a server problem. The servers should be decreasing the
MTU in response to the error.
3. If they aren't, it's a Cisco problem, unless there's something else
between the servers and the router that's building the VPN tunnel. Harass
the TAC.

We'd probably better pull this off the list if you have further queries -
it's sort of offtopic.
