More then 100 processes with 0% CPU

SYSTEM INFORMATION
OS type and version Debian 11
Webmin version 2.105
Virtualmin version 7.9.0

All of a sudden I get more then 100 processes with 0% CPU
They will never go away. Like this:

25 root 0.0 % [kworker/u4:1-events_unbound]
26 root 0.0 % [kdevtmpfs]

What could be the reason?
Can I limit the number of those to normal?

Which one of those processes do you believe is abnormal?

Is it normal that there are so many with 0% CPU
More than 150 lines. They don’t change except for those at the top.
They seem to be stuck there.

It looks normal to me. Those are mostly kernel processes.
