I recently upgraded from Snow Leopard to Lion, 10.7.4.  I'm running an iMac 3.3ghz Intel Core Duo.

 

When I open iCal the program gives this error message and freezes (requires force quit--nothing works): 

 

     The server responded with "509" to operation

     CalDavMigrateToServerQueableOperation

 

I cannot find any fix and the program is inusable.  This is very frustrating.  Any meaningful help will be greatly appreciated.

    Has this been resolved?  I have this problem too.  MobileMe created many duplicate categories (around 50-100).  Some have events in them, some are empty.  Do you have any duplicates?  That can cause problems.  I tried to go through them and delete the empty ones, but that is tedious work because the web app is so slow and the other apps wont list the events in the category, so I don't know if it's empty.  Anyway, after many hours of work, iCloud re-duplicated them! I'm frustrated.
