Some further info: My syslog was geting spammed with eCryptfs messages as per https://bugs.launchpad.net/ecryptfs/+bug/911507, but only when Thunderbird was in online mode.
The culprit was a zero length global-messages-db.sqlite-journal file under .thunderbird. I'd copied my .thunderbird directory from my old laptop (that wasn't using encrypted homedir) to the new laptop (which is using encrypted homedir). Moving the file out of the way stopped the eCryptfs spam, and dropped CPU usage from about 70%+ to about 54%, which isn't melting the laptop. Thunderbird has recreated the global-messages-db.sqlite-journal file, and it now has non-zero length. I guess what it's doing now is more normal. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to thunderbird in Ubuntu. https://bugs.launchpad.net/bugs/927515 Title: thunderbird uses excessive cpu power Status in “thunderbird” package in Ubuntu: Confirmed Bug description: Just received the automatic update last night. Ever since, thunderbird is using 20-50% CPU constantly, according to top. Turned off global search and indexing to no avail. This is really bad for me as it's driving up the temperature of my laptop, runs up the fan noise and reduces battery time.
