Nextcloud ZIP downloads keep running after canceling — server keeps working

Hello,

I’m running into a frustrating issue with my Nextcloud instance in Docker and I haven’t been able to fix it yet.

The main problem:

when I download a folder as a .zip from the web interface, the server seems to keep generating / processing the zip even after the client has already stopped the download. As a result, the hard drive keeps spinning for a long time, which is becoming a serious issue.

Context:

  • Nextcloud is running in Docker.

  • Image used: bigbeartechworld/big-bear-nextcloud-with-smbclient:33.0.5

  • I’m on ZimaOS.

Important symptom:

  • As soon as I cancel a .zip download, the disk keeps spinning instead of stopping right away.

  • It feels like the server keeps processing the zip on the backend even though the client has already stopped in the browser.

  • This behavior was not happening before the Nextcloud update, so I strongly suspect a version change or a recently introduced behavior.

What I have already checked:

  • The problem still happens even though the containers are running normally.
  • The issue appears specifically when downloading folders as .zip files.

What I’m trying to find:

  • Why the .zip download continues on the server side after the client cancels it.
  • Whether this is a known Nextcloud bug.
  • A reliable solution to stop the server / disk from working unnecessarily.

If anyone has seen this before or knows the real cause, I would really appreciate any serious leads.

Thanks in advance for your help.
