I didn't have the global-messages-db.sqlite-journal file; I did have global-messages-db.sqlite having ~400 MB.
After removing global-messages-db.sqlite and starting Thunderbird, it created new global-messages-db.sqlite and global-messages-db.sqlite- journal files. Thunderbird CPU usage didn't go down; it's still constantly 50%-100% CPU usage. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/927515 Title: Thunderbird stuck at 100% CPU To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-consumption/+bug/927515/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
