Almost 100% CPU Postgresql

Question

When I restart Postgresql 11, the CPU shows basically no CPU usage. But after a while the CPU is occupied by "kdevtmpfsi". What is this and how can I fix this?

1275    postgres    99.8 %  /tmp/kdevtmpfsi

you should check the various possibilities described there but: https://github.com/docker-library/redis/issues/217 "...This is not a redis issue. This is a known crypto mining malware unrelated to redis..."

google kdevtmpfsi, the results seem to indicate mining malware...
