RB 1100AHx2 went crazy

Hello,

I have an RB1100AHx2 that was running fine for two weeks now. Suddently this afternoon the device started to behave strangely. The netwatch that i had defined to watch over one internet link started flapping while the connection had no issues at all and the static route for the internal network on another interface was becoming unreachable and a few seonds later was going back to normal again. After i rebooted the MikroTik everything went back to normal again and nothing else happen since that moment. I am running version 5.20

Any ideas on what might happened to the device?

Thanks

RB1100AHx2 have problem in multi cpu supporting.
you can try with V5.21 or wait to up V6.x stable in mikrotik download center.
