Hight memory usage on macOS after a sync

[igorkulman]

Describe the bug
When I start Maestral and no Dropbox files change so nothing needs to be synced the memory usage sits at around 100 MB. Bug after I change some files and sync happens the memory usage skyrockets to more than 1 GB and never goes down, I need to kill the app and start it again.

To Reproduce

• open Maestral on macOS
• sync some files
• look at the memory usage

Expected behaviour
Even if memory usage spikes up when doing sync it should come back down eventually

System:

• Maestral version: 1.8.0
• Python version: 3.9.6
• OS: macOS 14.2.1 (23C71)

Additional context

"Idle"

"After sync"

[samschott]

That is indeed not working as intended. Maestral is typically very diligent in loading only small parts of files into memory as they are synced, at memory should be freed after each sync cycle.

Are there any particular patterns that you have noticed when this is happening, e.g., with particularly large files or with a large number of changes?
