Ok so I tried it with the mac of a colleague who has the Calendar.app 7.0 under Mac OS 10.9.5. The same Problem occured. Is it because I'm using the file system as storage?
That is a possibility as we really don't use or test the file system implementation any more (beyond maintaining it solely for the purpose of migrating data to the SQL DB). Still I am a little surprised this is happening as ETag handling is a pretty basic piece of the protocol - but if there is a bug we would likely tell you to upgrade since you have a pretty old server version. If you want to try and debug this further (rather than doing an upgrade) then please try and get HTTP protocol logs of a bunch of requests prior to and after a 412 response. -- Cyrus Daboo
