CPU Usage on RB1100AHx4

I have Dude Edition Routerboard and add the 1080 mikrotik devices on this Dude Server. I just use ping probe in the dude server becuse just I need to control ping of this devices.
But I have 100% CPU usage on this router…!!!

I import this Dude database on the Dude Server on 1036 by 36 core CPU also come of CPUs on the 1036 are 100%

in the Dude Router just Dude service is run and there has no any services on this routerboard.

Please advice me how to fix this roblem

Ros version? Profiler output? Where is the dude data storage placed?
