We have been running an ipsec vpn between 2 asg220's using the default triple-des setup for some time with no issue. Last night the log files started filling up at an alarming rate, 150-200mb/per hour, the odd thing is the vpn seems stable so I am rather confused.

Both asg's just repeat the same thing in the log files between 30 and 100+ times a second
Thanks for your time,
Matt
