Comment (by rootie):

 I'm quite technical so I'm sure we can find that issue together. Before I
 install this on my productive system I'd like to share a video I've made
 showing the memory leak. I'll try to exactly explain again what my setup
 is and what I've done to reproduce it.

 - Updated to the newest Cyberduck version 7.4.0
 - Logged onto OneDrive and selected Sicherungen\Eigene Dateien\Musik -
 this is an online only vault and NOT synched to my hard drive
 - Inside the "Musik" folder there are 3 sub folders and within those sub
 folders there are tons of other folders with singles and albums. Basically
 this is my (legal!) backup of all my music sorted in sub directories
 - I drag and dropped the "Musik" main folder onto a finder window. I did
 NOT select single files - I want to have the whole "Musik" folder
 - The preparation of the files and directories starts which took about 30
 minutes. During that time no excessive memory usage was there
 - After the preparation the download has started and as soon as this
 happens the memory usage goes up

 I monitored it with the terminal and the "top" command. Maybe you did not
 try with a directory or drag/drop and that's why you weren't able to
 reproduce it.

 I can offer you a TeamViewer session together with a telephone call. This
 might ease up things significantly if you're still not able to reproduce

 Best regards
