How big is the route table on the 7201? I saw a very similar issue with one of our four 7200s when I started working with Zenoss as well. That one 7200 did have a newer IOS then the other three, but what I also realized is it had a full Internet 1 and Internet 2 routing table. When Zenoss would go to walk the routing table is when it would spike and Zenoss time out. Of course if I cranked up the timeout on Zenoss I would kill the router for that much longer. In the end I removed the routemap plugin from that device. I later got the Network Engineer to look at it and he found that it was mis-configured and should not have had the entire Internet 1 routing table loaded (just peer networks and Internet2). After that I was able to put the routemap plug-in back in and it was fine. My other word or warning is that if you do have a large route table I'd suggest you switch Zenoss to only load "local" routes into its DB not the routing table. I found that I wanted more then just "local" routes but not the BGP routes in Zenoss, so I hacked the routemap plug-in to also load ospf and is-is route entries when I had "local" routes selected.
