https://community.extremenetworks.com/t5/extremeswitching-exos-switch/process-system-99/m-p/42004#M9827 Hi <BR /> <BR /> I´m having this problem with some summit switches I have, once in a while I lose conection with my switch this happens once or twice per day, I notice this because of my monitoring tool. I have been checking my switch and executing the command show cpu-monitoring I have notice that process like System, fcoe and hal are always at 99% of utilization, this happens even when my network traffic it´s at its lowest. How normal is this and what can i do to fix this?<BR /> <BR /> Thanks. <BR /> Tue, 03 Jun 2014 23:28:00 GMT Erick_Cruz 2014-06-03T23:28:00Z https://community.extremenetworks.com/t5/extremeswitching-exos-switch/process-system-99/m-p/42004#M9827 Hi <BR /> <BR /> I´m having this problem with some summit switches I have, once in a while I lose conection with my switch this happens once or twice per day, I notice this because of my monitoring tool.
