Since upgrading I have some major problems with my calendars:

* on my own calendars each time my iphone checks in or fetches new items it creates a new empty calendar with the name that looks like a UUID
* calendars shared with others, when logged into their accounts from an iphone the shared calendars are read only while in the web ui they have the full rights

The web admin interface also keep reporting that my server is down - in my server logs I see it ssh to the local machine and presumably run some command, this must fail so it claims services are down. Not sure what gets done via the SSH

any suggestions welcome. Otherwise I will need to figure out how to downgrade which is probably going to be horrible
