VPN 3000 high CPU

Unanswered Question
Sep 3rd, 2008

Hello... Is there any known issue other than RC4-128 SSL encryption for WebVPN and data compression that would cause a VPN 3000 CPU to spike to 100%? Thanks.

I have this problem too.

Thanks. There are two CryptIC encryption cards in slots 1 and 3. Both are in operational status but only one is encrypting and decrypting. However, the title bar is titled SEP not SEP-E.

Thanks Andrew. We'll look into adding the SEP-E module. Wouldn't that cause consistent high CPU utilization? We've only seen the CPU spike twice to 100% and stick. Normally it's around 2% so there's not much load on the concentrator. We thought there may be a known bug in the IOS.
