Re: HA_EM-6-LOG: cpu_stats: ------HIGH CPU DETECTED----, CPU:

Thanks David. The device hits 80-90% CPU every few minutes. The techs
looking at it are saying that periodic CPU util of 80-90% is normal. That
doesn't sound right. Even if periodic, if the switch experiences 80-90% CPU
util, performance will degrade. Am I right?
