Will strace Tbird next to see what shows up.
Thunderbird runs two processes now:
$ ps axf | grep bird 15520 ? Sl 16:48 \_ /usr/lib64/thunderbird/thunderbird-bin 15585 ? Z 0:00 | \_ [thunderbird-bin] <defunct> 15590 ? Sl 0:00 | \_ /usr/lib64/thunderbird/thunderbird-bin -contentproc -childID 1 -isForBrowser -prefsLen 1 -prefMapSize 280054 -jsInit 285716 -parentBuildID 20220502180952 -appdir /usr/lib64/thunderbird 15520 tab
The second seems to be some web-browser process, likely for displaying html messages or web-pages in the message window. I have thunderbird running on a separate desktop where it is the only app running, so while strace was occurring, I was on another desktop ensuring that thunderbird received no input or focus.
The problem is both processes are extremely active, a large majority of the entries are:
recvmsg(4, {msg_namelen=0}, 0) = -1 EAGAIN (Resource temporarily unavailable)
<<snip>>
This strace output is all beyond my knowledge, I can't really offer any insight there. After another few days without noticeable spin-ups, the fan kicked in again just now when I was watching a YouTube video, but it was Thunderbird that had the CPU activity. I was seeing this a lot a week or so ago.
