    Cisco 3640 grinding to a halt

    I have monitored this router over the course of the evening, and can find nothing wrong with it other than the increased cpu usage. Any ideas on what could be doing this?

    Cisco 3640 grinding to a halt

    If I reboot it, it runs great for about an hour or so... then it bogs down. I don't think it has to do with routing, since it even lags from the inside of our network. I don't have a console cable to hook up to it.

    Cisco 3640 grinding to a halt

    I work for a medical company, and we are using a cisco 3640 with ios 12.2 as our main vpn / internal nat router. About 4-5 hours after a reboot, the router slows to a screeching halt, no ping... but can telnet. the delay when entering telnet commands is 1-3 seconds. I have tried the sh ip cache...
