Hello people, My openhaibian pi4 has a networking issue. The device stops accepting new connections after a while. Current connections remain working. New connections fail. Outgoing connections are working. There are no firewall rules. The only way i can get new connections is to restart. Every thing else is working as expected.

Do you have any ideas how i can fix this.

Are there any log entries in /var/log/system.log file and/or information returned by the dmesg command that could be of help to identify the root cause ?  
What about the amount of memory that is in use and how busy are the CPUs ?
