Hi, http://rainbow.chard.org/2013/02/19/thunderbird-high-cpu/ worked for me, dropping CPU usage to almost none.
I noticed that the problem surfaces after extend time (several days) of being offline and re-syncing remote IMAP folders on multiple accounts in parallel. TB was at 100% CPU, causing the CPU fan to spin up to max, and unfortunately even on my TP x201 these fans are not built for running at max rpm all the time, so it died upon me and I had to replace the heatsink assembly ... this was of course an unlucky combination of this bug, dust in the heatsink, running at max RPM, and a kernel bug that messed up fan control, so TB alone was not the one killing my fan ;) -- 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/thunderbird/+bug/927515/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
