CPU Usage 100% Need Help

I’m using a 750G routerboard with hotspot validation (IP and MAC) routing with proxy arp. i’m having problems with the cpu usage, the CPU goes to 100% and when i see the profile new tool the process called flash is the one that is eating up my CPU…

What could be the problem? i’m not graphing i’m not logging nothing! why flash uses my CPU then…

I’m using 5.0rc3

disable all unneeded packages

Thanks Alex, that works perfectly!
