I have CalendarServer 3.2 installed on Ubuntu Precise. I got the
package and a couple of dependencies from the Quantal repo and
installed them manually.

It runs well, but I notice that I get this error in
/var/log/caldavd/error.log every five minutes:

As far as I know, it's not causing any problems as a result, but it is
filling up the log file. What might be causing it?

Thanks
