Just hooked this up today and with Vibhor's help I have the DMZ working with nothing but a test server in it replying to ping. But I noticed that the firewall slowed down after about an hour when I was viewing the configs and whatnot and I did a sh cpu usage and got this back:
LINTHpix515# sh cpu usage
CPU utilization for 5 seconds = 96%; 1 minute: 96%; 5 minutes: 97%
Very high, what do I need to look for?
