By any chance were you querying a Sup32 that had BGP full routes? That and =
other large tables can easily swamp the cpu on the Sup32.
This technote is based on IOS, and I don't know if the same facilities exis=
t in CatOS, but as Nick mentioned, run, don't walk and convert to IOS. CatO=
S is dead.

Subject: Cisco 6509 SUP32 SNMP Meltdown With CatOS
Anyone have experience with Cisco 6509E/SUP32 crashing under heavy SNMP
polling load, causing high cpu utilization and 6509 lockup, requiring 6509
reboot? CatOS is deployed. Is the behavior any different with 6509 IOS?
David
