We have an active cvpn3030 with 85-100 users with tunnels up at any one time. A combo of PPTP and IPsec client sessions and a couple of IPsec lan-2-lan sessions. Twice now in the last three months the box has frozen up. The first time this happened TAC asked me for log files - but by that time the logs had rolled over and into cyber oblivion. (Funny how these things never happen when you're in the office or near a computer.) Anyhow - I wound up upgrading to 3.5 from an earlier version because of this same problem. 3.5 has definitely lessened the frequency - but the problem still exists. Can anyone with a similar amount of traffic or more confirm the issue? Is there a version that is still more solid? Thanks.
