Hi All,
Am getting RE High CPU utilization frequently on the NMS server. it keeps appearing after every 30mins or less and stays for like 20~30 mins and then resolves. when it appears, if i chech "show chassis routing-engine", i see kernel usage is 9%, users is 5% and roughly ~86% is always idle. not sure why it says high utilization when more than ~80% os idle.
i have run the "show chassis routing-engine" several times and all the time, there is no single process using more 10%.
we have done recent junos upgrade from 15.1 to 17.3R3-S2.2, i have also noticed that "comit" takes long after the upgrade.
