I've got a personal project that I recently upgraded one of my pix's up to a 5505. After getting the tunnel setup, I noticed that
the tunnels would not come up. and while troubleshooting the 5505 would just reboot. Now this 5055 is running tunnels just fine
to another 5505 and no issues. But after about 5 minutes of the ISAKMP tunnels trying to get up for no reason at all, the ASA would
reboot and not give a reason. I'm running syslog server here and can see that PHASE 1 is completing but having issues in phase 2
then just blows up.
When it comes back online, if I shut down the tunnel to the PIX then I won't have any issues.
I'm thinking after doing some research that I might need to not use the site configuration tool and use the CLI to specify the encription instead
of the auto.
I am going to go try that, but has anyone seen this issue before?
