Hi All

Thank you for all the effort that was put into resolving this issue.
I was able to leave my server off until today, not everyone can do this, and waited for a solution - i just ran the update from the web interface the moment i booted.
After the update ran, i also did:

systemctl stop clearsync.service
rm -f /var/lib/csplugin-events/events.db
systemctl start clearsync.service

Everything is now responding and i do not see any more log files going "NUTS"

Thank you again for everyone involved

Leon
