<p class="MsoNormal">That may have actually done the trick. We aren't using any snmp tools on this box, but I added no snmp-server to the config and that brought cpu back down to 1%. I'll keep watching and see where it lands.<br>

If there are any other thoughts, feel free to send them over. I appreciate any input.<br>

Can you eliminate any SNMP tool, that might spin the CPU around?<br>
