Recently,we have got some kind of problems on HiperARC Card funcationality. When we Issued "Show CPU Utilization", it shows that the CPU Usage is fully occupied 100%. Fortuantely, we found a temporary solution for the case. "Clear ARP_Cache". It cause to decrease the CPU process but not permamently. Ps.The pool for clients is Valid IP Range and no NAT Policy performed. CPU Utilization: Instantaneous : 99% Last Minute : 70% Last Hour : 70% Last Day : 40% Any Idea? Regarsd Sharouz
