Keep getting disconnected ungracefully

Hi,
Im now trying to install an evaluation version on azure aks and it created a pod and the pod will restart constantly caused by OOM exception. I looked into the event log file after a new deployment. It was full of
Info like
“2020-10-13 15:30:58,305 - Client ID: UNKNOWN, IP: 10.x.x.x disconnected ungracefully”
almost every second.

Do anyone knows the cause of this problem?

thanks
