Steps to reproduce:
Use Thunderbird. (Multiple mail accounts, no add-ons.)
Problem occurs completely randomly, as far as I can tell.
My .thunderbird folder has 3.9 GB at this point, so maybe it’s got something to do with that?
I have a log file of one instance that showed this behavior (setting all levels to 4 (debug) in $MOZ_LOG), but it’s 150 MB so I’d need to know what to look for. (It’s got 126k debug messages, 1.3M info messages and 1.3k warnings.)
Actual results:
Suddenly, CPU load for the process goes to 50-70% and stays there, slowing down the whole system (to the point where typing lags). (I have four 3.4 GHz cores.)
Expected results:
CPU load should have stayed where it’s supposed to be.

such a large logfile isn't likely to be useful.
A profile is needed, but I'm not sure that is working yet.

Thomas,
Please run the performance profiler:
-
install profiler add-on into thunderbird - download the file from https://github.com/firefox-devtools/Gecko-Profiler-Addon/blob/master/gecko_profiler.xpi?raw=true and in Tools > add-ons click the gear to install add-on from file
-
Follow instructions at https://profiler.firefox.com/ (videos BASED ON FIREFOX at https://profiler.firefox.com/docs/#/./videos-intro )
You must be using current nightly build from https://archive.mozilla.org/pub/thunderbird/nightly/latest-comm-central/
And backup your profile before testing - https://support.mozilla.org/en-US/kb/profiles-where-thunderbird-stores-user-data#w_backing-up-a-profile
