Nextcloud client doesn't close connections to Apache2

[Byggvir]

My nextcloud client on a Samsung Galaxy Note 4 opens lots of connections to the server and doesn't close these connections. (CLOSE_WAIT) Apache2 starts a lot of tasks which consume 100% of the processor resources. Nextcloud client and Nextcloud servers are not usable.

GitMate.io thinks possibly related issues are #2492 (nextcloud does not handle connection failures in uploads), #2073 (nextcloud doesn't know how to open .love files), #527 (Cannot connect to Nextcloud Instance (stuck at testing connection)), #489 (Nextcloud app doens't close), and #1806 (Nextcloud android app doesn't connect).

This is strange. Can you see which connections these are? To which endpoint?

@nextcloud/server-triage have you heard something similar? Mostly we use dav endpoints on server and they return always a proper message back, which then should lead to closing the connection, or?

Soory. It seems to be problem of the Apache server. After deactivating nextcloud the problems came after some time back.

Have the reinstall the server and in the moment it's working. Can't investigate the problem anymore.
