I have a 3750 with IOS Version 12.2(25)SEE3. Once or twice a day i have alarms on High CPU utilization on the switch. "HL3U bkgrd process" , is the process which is eating up my CPU. I try to Google but cant find the details of this process anywhere. Has anybody some info about this process ??
Further, during the search i read this on cisco.com, it says : "A capacity issue is one of the symptoms of high CPU utilization on Cisco IOS routers. However, a capacity issue is almost never a symptom of high CPU utilization with hardware-based forwarding switches." Please elaborate it.
