Steps to reproduce

1. Set up Nextcloud AIO
2. Import calendar with 400+ entries

Expected behavior

The calendar gets imported

Actual behavior

After a few seconds several errors appear and the site reloads. The calendar is only partly imported.
The same thing happens when trying to import contacts and possibly when uploading many files as well.

It seems that somehow new database connections are endlessly created until the system fails.

Host OS

Ubuntu 22.04

Nextcloud AIO version

v1.5.0

Current channel

latest

Other valuable info

Here is the relevant section of nextcloud.log:
nextcloud (1).log

There are no errors in the postgres or nextcloud docker container logs.

Note: I have followed the migration guide to migrate my old files.

So there is really nothing in the postgres logs? It sounds like there should be something as the max connections seems to be reached...

Either way I fear there is no good way to fix this on our side. The import should rather not open as many databaae connections... Please report this to the calendar app!

However I'll move this to discussions to see if we should raise the max connections value.

Seems like there is indeed one: #966

Lets handle this further in #966
