Calendar freezes #6235

Open Julia-TGC opened 1 month ago

Julia-TGC commented 1 month ago

Steps to reproduce

We're unsure what triggered this initially and cannot reproduce it outside of this server. A user was making a regular change to an event when the issues started.

  1. Enable calendar app
  2. Go to calendar in the web interface.

Expected behavior

Calendars should load, webUI should function, and the calendars should sync with thunderbird and DAVx5

Actual behaviour

When opening the calendar app, the web interface freezes, multiple calendars are indicated with a loading circle, and the entire web interface becomes unresponsive. No calendar can sync to a client.

When the Dashboard was enabled, the whole web interface would immediately freeze when it tried to fetch calendar events.

Everything else works fine when the Calendar app is disabled.

Additional info

We first encountered this issue in Nextcloud v25 with the 4.6.8 calendar app. We had a upgrade scheduled and found no issues upgrading to 26 and then to 27 but the same issue persists. Most of the calendars are shared internally. When looking at the calendars in the webinterface, the shared calendars seem to perpetually load while the 'personal' calendar does not.

Can you try to provide browser logs as well? Open F12 before accessing the app.

Ah, I checked it with the app already open, and it didn't show me any errors, so I did not add it. It did this time. See attached.
