Hey, in the meantime I determined, that the high cpu occured after updating to firmware 6.7.x.x in the past. I´ve downgraded the stack to 6.6.x.x et voilá the cpu goes down to normal. The Dell-Support accepted the downgrade as the solution and seems not to be interested to find the root cause in the newer firmwares.  Regards, Thorsten    
Hi, does anybody determine way to high cpu on N1500 stack after upgrading firmware to 6.8.0.1 due ssltHelperTask? [IMAGE] The stack contains 4 x 1548p units. I rolled back to 6.7.1.10 because the switch had paketloss and high leadtime regularly: [IMAGE] What I noticed too, after reloading the stack, the poe-module of unit 4 did not come up. After reloading unit 4, it worked again. I have no screenshot but "sh power inline" shows unknown status of all ports of unit 4. Regards, Thorsten
