I'm hoping someone here has some experience with Cisco Concentrators. I have a couple of 3005 VPN concentrators that drop off the internet at random. This started after I upgraded the Software and Bootcode at the recommendation of Cisco's TAC to fix the recent IKE vulnerability.

Is anyone aware of problems with the Bootcode? That is what I'm leaning towards because it doesn't look like a power problem. I've also tired several software version to no avail. Switches aren't showing many errors either.

Any thoughts?

Thanks.
