Systemd/-container port limitation after to many hits

[john doe <johndoe65534@mail.com>]

Hi,

I'm playing with systemd-container on Debian 10 (Buster).

I have mpd listening on port 8000 insite the container.
Networking between the host and the container is working fine but one
port (8000) in this case is not:

mpd [10.0.1.147] 8000 (?) : Connection refused

It looks like systemd/systemd-container is blocking port 8000 because to
many connections has been made to port 8000.

If I reboot the host port 8000 works again.

Looking online didn't help me find why systemd would block a port.

Is there any options in systemd that would limit port connection or any
ideas?

Note that the name of the container is 'mpd'.

Any help is appriciated.
