So the CRM machine remains unplugged until we can determine what odd behavior was causing all this strange traffic and freaking out the Cisco router. It sat at 30% CPU utilization until after we rebooted it, then returned to normal. No odd processes were discovered running - though that isn't a certificate of a clean bill of health.
Back in the saddle again
Sean Doherty is working on a review and taking advantage of our infrastructure. Sometime yesterday we lost all connectivity between our Cisco router and our provider's CPE. Turns out the router was running at 99% CPU utilization and was dropping packets faster than a well configured firewall fending off MSBlast. After trying a few tricks, which did not help, I pulled every connection from the switch hoping to use process of elimination to find out where the errant packets were coming from. Everything went well until I plugged in our CRM machine. Wham! The router became unresponsive and packets starting dropping. I unplugged it and all was normal after the queues cleared out.
