The event database might be corrupt

2. Delete the event database on command-line
  rm -f /phion0/event/event*

3. Delete the event buffer database on command-line
  rm -f /opt/phion/preserver/eventd-buffer.db*

4. Start the "event" service again via GUI.

Note:
Events that could not be reported due to a corrupt event database will nevertheless have been logged and can be viewed in the Logs GUI
