It looks like your accounts.xml file contains a group which has a missing member. Check the <members> of each group and make sure each <member> exists in the accounts.xml file, and is of the specified record type. On Aug 15, 2012, at 1:23 AM, Jane Atkinson <jea62q@xtra.co.nz> wrote:

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
