      Hi,

      I am using z-push with the kopano backend. From time to time my iPhone battery drains super fast and everytime the same thing: Log into my z-push server, inspect the logs, finding entries like:

      [...]

      I hoped I would be able to pin-point the messages to a particular element (appointment or task which has inconsistent data) which I could delete then. After enabling WBXML debug I zoom into the error message and see:

      From my understanding both issues (the error message and the loop) is caused by the element with the ID U1b889 which is the folder “Calendar”.

      That’s clearly not something I can delete because it includes my entire calendar!

      Any hope to fix this?
      Thanks!

        Having the same problem. Feels like it started with iOS 13. Tried running kopano-fsck and re-added the account a couple of times. Re-adding the account helps for a couple of hours/days, but the problem comes back after some time. Feels like it starts showing up after creating an calender appointment.

        https://forum.kopano.io/topic/2726/mobile-loop-detected/8 describes the same problem.

          Hi @divB @baurmatt,

          did you try my suggestions from https://forum.kopano.io/post/15163?

          If that also doesn’t help, try removing the ActiveSync account from the device, remove the device with z-push-admin, restart the device, add the account again.

          @divB you are using a quite old Zarafa version. Consider upgrading to a recent Kopano Core version.

          Manfred

            @Manfred I tried a couple of things:

            1. Clear loop
            2. Resyncing
            3. Remove the account from the phone without removing it in z-push
            4. Remove the account from the phone and removing it in z-push

            All of this didn’t help and/or the problem showed up sooner or later. I’ve just did 3 again this morning. Next time I will try to reboot the phone before re-adding the account.

            FYI: I’m running the latest Kopano Core/z-push version.

              @divB said in Suffering from sync loops:
              Try a different mail app. i have seen simular things on android. due to… i still have one zarafa 6.30 running with an old z-push.
              I also notice with some apps, that if they have a mail and contacts and callendar, you need to install all of the same supplier.

              0x8004010F - code: 12, if its the same as on a real exchange, disable GAB in z-push is worth a try.
              or create one that the use can access.

              if in the mail app, an option exist about offline adress books, disable it.

              A few suggestion you could try, to keep it running, but upgrading is the best option.
