    It was no updates in this day.
    All i did is installed fail2ban with 2 additional packages: python3-pyinotify python3-systemd
    Now fail2ban and these packages uninstalled.



  • update: i installed kopano-ical in separate server ( wit server_socket = http://my_kopano_IP:236/) for test.
    same problem.
    so it’s not kopano-ical service problem , it’s kopano service problem



  • update2:

    problem only with MacOS Calender ( with https://host:8443/caldav )
    only MacOS crashed service.

    But it start to do it yesterday. MacOs didn’t updated.



  • update3:

    this problem on all kopano servers i have.
    different servers and different macos clients.

    so it’s global problem



  • update 4:
    problem only with MacOS Catalina 10.15.1



  • This issue is already known. Check KC-1634 for more information. It will be solved in Kopano 8.7.8



  • @nschoote thx!
