I can confirm this.After upgrading from bullseye (oldstable) to bookworm (stable), transmission-daemon 3.00-2.1+b1 uses much more memory than 3.00-1 before.
It used to average at about 700 MB and never used more than 1 GB. Now it grows linearly. After a week of uptime it's currently at 3.2 GB. I noticed because the machine started swapping for the first time ever. -- ilf If you upload your address book to "the cloud", I don't want to be in it.
