Problems and solutions

When Raspberry pi keeps the IP and stops network communication: You can clear that buffer by reading from it (cat /dev/xconsole), but then it'll fill up again over time. You can also remove a bit of configuration to stop that buffer being used.

As root edit the /etc/rsyslog.conf file and remove the following lines from the bottom of the file. daemon.;mail.;` news.err;\ *.=debug;*.=info;\ `.=notice;.=warn |/dev/xconsole

(you could also comment them out by putting a # at the start of the lines)

You can then restart the rsyslog service with sudo systemctl restart rsyslog.service

How to remove/uninstall restartd sudo rm -f /etc/init.d/restartd /usr/sbin/restartd /etc/init.d/restartd Restartd is useful service for some cases.
