I'm using transmission-daemon (transmission 1.73) on Ubuntu 8.04 occurs bug: in handling through the webui (or transmission-remote) interface is not shown (transmission-remote writes timeout), but the list of transmission-daemon starts to load CPU and memory to hold 90%.
It seems this happens when a torrent is removed from the tracker
This helps the removal of unregistered torrent from "/var/lib/transmission-daemon/info/resume" and "/var/lib/transmission-daemon/info/torrents"
Sorry for my english
