I get this msg on my router all the time. It's related to the Tunnel, but I don't know how to fix it.
Dialer0: the fragment table has reached its maximum threshold 16
The memory usage of the router is always at 80% also.
It's a 837 router.
Can anyone guide me in what to do?
Thanks
Bernard

I think you're hitting a bug. You should change your version of IOS. That will probably fix it.

It could be a DOS attack against your network. See the Cisco article below:

I know you can increase the table size with the
ip virtusl-reassembly command but I don't have the recommended specs handy.
