rootless docker issues with on access scanning (eset_rtp) on RedHat EL 8.5

[mensch 0]

Hello,

we have a RedHat EL 8.5 server running containers in rootless docker mode. 
If On access Scanning is enabled it slows down the containers a lot AND we see the following eset_rtp messages in /var/log/messages:

The commands AND paths mentioned in the eset_rtp logs above ARE mostly inside the container. For example: "nginx" is running in the container.
