I have not researched the 3600 IOS issues (what's available), but I know we
found 11.2(22A) was the only stable IPSec version for the 4700's. Crazy as
it may seem, this was proven after a month in the lab. You may need to back
way down in version, & you are right- generally the disappearing interfaces
is software issued. In the past (for me), this was caused by incompatable
boot ROM's too.
Check with you Cisco rep. & take his or her advice with a few teaspoons of
salt :-)
Good Luck !!!
Phil
