I am encountering this issue where the IPsec tunnel drop frequently and unable to recover for at least 4-8 hours. At my end I am constantly seeing message as follow:
Nov 10 2012 08:11:27: %ASA-4-713903: Group = X.X.X.X, IP = X.X.X.X, Received encrypted packet when crypto not active!!
Nov 10 2012 08:12:02: %ASA-4-713903: Group = X.X.X.X, IP = X.X.X.X, Received encrypted packet when crypto not active!!

Anyone can shed some light of what could went wrong?
Thank you.
