I'm new here so please let me know if I posted in the wrong forum. Anyway, I have a strange problem that I have been unable to nail down recently. I have two 2800-series routers trunked on physical ports to each other, along with a switch connected to each router, forming a square of sorts. The routers have primary and backup HSRP interfaces configured for each VLAN (there are 9 VLANs). Right now traffic is flowing through the primary router; randomly I'll notice that I'll lose connectvitity to the primary HSRP gateway, and will be unable to send traffic to other subnets (SVI VLANs) for several minutes (without changing the gateway). I also notice the router's CPU usage spike up near 99% while this is happening. The last time this happened I was remoted into 3 different machines, and had a couple context windows up in each session. Has anyone encountered anything like this? I was thinking perhaps some asymmetric routing is occurring, but I'm not sure.
Any help is greatly appreciated.
