OmegaWiki has a technical problem; there are certain records that have problems and that crash the database. There are solutions to this problem and some are being tested at the moment.
This week I was in Bamberg at the Otto-Friedrich University, and discussed this with Martin Mai. He has now build a monitor that checks if OmegaWiki is still alive. This works fine. We now have permission for the Bamberg Nagios service to run a script when OmegaWiki is no longer alive.
This will solve one of my biggest worries which is the availability of the OmegaWiki service.
