I too was experiencing this issue on Ubuntu 10.10 x86_64 running Deluge 1.3.1.
After a few google searches, I discovered that my issue was related to the "Open Folder" option in the torrent context menu. Full details here: http://dev.deluge-torrent.org/ticket/1396 I've stopped using that option 2 weeks ago and I haven't experienced this issue since. ** Bug watch added: Deluge bug tracker #1396 http://dev.deluge-torrent.org/ticket/1396 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/660365 Title: deluge uses 100%+ of CPU when using full allocation -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
