I am also reporting that I have an issue with memory leaks after upgrade from Bullseye to Bookworm, where transmission-daemon changed versions from "3.00-1" to "3.00-2.1".
The process gets killed because of OOM: transmission.service: Main process exited, code=killed, status=9/KILL It would be really nice if this gets fixed in Bookworm/stable. Until then, I have added the following to the /etc/crontab, so that transmission-daemon gets restarted every 6 hours at particular/conventient time. 15 3,9,15,21 * * * root systemctl restart transmission
