We have a customer which has a VPN concerntrator model 3005. They have been complaining that over the last 6-7 months that connectioned from about 20 remote sites (L2L) have been running very slowly. This occurs especially when the VPNC CPU shows that it is running at 100%. As soon as this drops, it all returns to normal. However, it is intermittent and even when there are minimal active sessions the CPU goes to 100%. The VPNC has 64mb ram and the usage is a mere 30%...Can anyone explain what is going on? The remote sites are running cisco routers over broadband. Which pass through a PIX 515E (via ACL) to be authenticated on this VPNC.
