CPU Mgmt Port Hight Utilization and Excessive Traffic

Hello,

I see this error on 3 out of 7  of my switches, after which the switch reboots itself. I had SolarWinds management software installed on a server and monitoring the switches through the management port. I thought the issue might be with solarwinds putting excessive traffic on the management port. I have disconnected the management port but am stull getting this error alongside cpu errors. What do you guys think?
