Updated to Nextcloud Desktop Client 33.0.0 this morning, and I’ve now been seeing consistenly high memory usage (~5GB) while idle.

This hasn’t happened on previous version or even today before updating, the Nextcloud server hasn’t had anything changed since updating, so I’m not sure what’s going on.

Steps to replicate:

  1. Install Nextcloud Client 33.0.0

  2. Add an account to sync

  3. High memory usage

Info

  • Nextcloud Server version (e.g., 29.x.x):
    • 32.0.6
  • Operating system and version (e.g., Ubuntu 24.04):
    • Ubuntu 24.04.4 LTS
  • Reverse proxy and version _(e.g. nginx 1.27.2)
    • nginx 1.29.6
  • Is this the first time you’ve seen this error? (Yes / No):
    • Yes
  • When did this problem seem to first start?
    • Today (24/03/26)
  • Installation method (e.g. AlO, NCP, Bare Metal/Archive, etc.)
    • AIO

Update, turning off “Use System Proxy” for my connection clears out all the memory, and then memory usage slowly increases over time again, no matter if I leave it on “No proxy” or “Use System Proxy”

Created a bug report for this as it seems to be an issue with the Desktop Client and “Cookbook” app.
