I have a similar problem. I have not found a solution, but I can
share what I have found so far:
1) The problem seems to be limited to iOS devices. I have only
tried using caldav, but each iOS device that I connect to this
person's calendar will not pull down the complete calendar. Any
Android device I connect with caldav-sync works fine.
2) Like you, I have found nothing in the logs to indicate a problem.
3) I have not been able to trace it to a particular event, I
think the problem is the number of events rather than the
content. I can't find an easy way to purge old events. Even if I
do delete them from thunderbird, they seem to stay in the
database on SOGo.
4) I have tried exporting and re-importing with sogo-tool as
well as exporting to an ics and then importing it to a new
calendar. Neither was successful.
Thanks Dave. I'm glad to see I'm not the only one who has noticed
this problem. I did find reference to a 25,000 event limit for iOS.
Although I haven't been able to confirm it, it seemed to help by
purging some of the older events. And, yes, since sogo-tool won't do
it, The user had to login to the Web interface and then change the
filter to all for the list of events. This resulted in a full
chronological list. Then the oldest events could be deleted in small
batches (a large group of selected events did not seem to delete
properly, however, a smaller selected amount, say about two months,
worked). Interesting that you mention about those events not being
removed. I didn't check to see that those were gone. I just sort of
assumed since they didn't appear in the calendar any longer, that
they were actually removed.
The calendar on the Mac desktop doesn't seem to have any issues and
includes all events so the code is obviously different. Apple seems
to tweak the CalDAV code with each release, so I'm guessing this is
the cause and SOGo is not longer as compatible as it once was with
iOS. It's particularly troubling as some events in a day will sync
where others will not. I would report a bug on this, but I don't
even know where to start due to the lack of telemetry data in the
logs. If I can find a way to increase the logging data, perhaps that
will shine a light on the problem.
Dave-
I have since requested the same user's calendar to an iPad with same
version of iOS and it works perfectly. There must be some other app
causing an issue on the phone, or, perhaps an issue with the phone
itself. I've also substantially increased logging inside SOGo and still
don't see any errors. I've also backed up and restored using sogo-tool.
Nothing seems to work. I'm curious if you were able to find out what is
wrong in your situation?
Steve
Steve,
No, I never did. I also tried setting up an iPad with the same
calendar and had the same problem of not all items pulling in. The
difference was that it would pull in a *different* set of events, but
not all of them.
