RB2011UAS switch ports flapping

Hardware MikroTik hardware general

Hi,
I’m using RB2011UAS, RouterOS 6.47.8.
For some weeks now, I notice every some minutes flaps on the ports of switch1, ether1 to ether5, about 2-3 secs in duration

ether5_5x link down
ether5_5x link up (speed 100M, full duplex)

I haven’t changed anything in the configuration or network topology.
Do you have any ideas? Can it be due to a hardware failuire?
Thank you very much in advance.

Downgrade to 6.46. Fixed it for me.

Same issue on RB3011. Please fix this Mikrotik.
