Answering myself: Kafka Server spawns only 1 process.
htop by default also shows threads, which was misleading. It can be turned off by pressing H https://unix.stackexchange.com/questions/10362/why-does-htop-show-more-process-than-ps Regards, Sven Gesendet: Mittwoch, 27.

I have a setup with CentOS plus Docker plus Kafka Server container based on the image of Confluent Platform 4.0.0 In ps -Alf there is only one Kafka process, but in htop I can see many. Regards, Sven
