CalDav no longer working from iPhone

[dcardamo]

I'm not certain, but this may have broken since a 5.0.16 -> 5.0.18 upgrade. I used to be able to get my iPhone to view my calendars and events using CalDav. A week ago it stopped updating to what Zimbra had as content. So I deleted the calendar account on the iPhone and recreated it. I can see the calendars, but no events are visible. This is in mailbox.log:

Any ideas what may be going on? Leopard iCal appears to be working well still with the same settings.

Just to throw this out there for troubleshooting - can you reproduce the problem on another zimbra account?
