Thunderbird 102 sporadically high processor use, consumes tons of power on idle. Calendar activity in CalDavSession.jsm
Thunderbird 115.0 (though also happened on 102), M2 macbook pro; OS up to date.
On AC & battery, thunderbird uses up huge amounts of power sporadically in its background activity, taking up ~50-80% of processor power & hundreds of gb virtual memory (see activity monitor screenshot attached). Computer gets pretty hot to touch with thunderbird on, which I don't see with other apps. Troubleshooting info below.
This has been happening for several months now, since I switched to thunderbird & was hoping it would resolve at 115. I can't find any correlation with other usage patterns of the computer (ie I dont think it's correlated with idle usage, but not willing to stage reputation on that).
Thanks so much for any help!

You haven't posted this somewhere else, correct??
I've seen this two or three times in the past 5 months, also on mac, reported as https://bugzilla.mozilla.org/show_bug.cgi?id=1839256. Though so far unclear it is strictly Mac.
A profile from you using https://support.mozilla.org/en-US/kb/profiling-thunderbird-performance will help
Actually I also posted it on Reddit yesterday, I didn't realize that you also check there too. Summary of my troubleshooting so far was that it does also overheat/occur during troubleshooting mode, and I captured a profile that you can see at:
https://share.firefox.dev/3rpOdS2
Not sure if I'm imagining this, but the problem seems to stop sometimes when I open up Thunderbird. Again, not sure if that's true, but I have a vague feeling that it may happen more as a background process.
Thanks! Shivam
Your issue also reported at https://www.reddit.com/r/Thunderbird/comments/14z04ky/thunderbird_115_insane_power_drawbattery_use/ is not the same as mine.
https://share.firefox.dev/3rpOdS2 points to calendar, with the majority of activity is in caldavsession and gc (memory garbage collection).
I have updated the title to reflect the problem occurs in version 102.
Thank you! Please let me know if there is additional info you need from me, happy to provide as needed. I can also switch to daily builds if there's an update shipped that you think may address this issue.
Do you have any events or tasks that have are recurrring/repeats?
I have some recurring events in the calendar, but they're all ~once per week and uncorrelated with the overheating/processor use. No tasks at all.
Not sure if helpful, but I got a new m2 mac mini and I experienced a similar issue: https://share.firefox.dev/3K7sAMC
(see also CPU usage in attached image)
May be unsurprising because I cloned my macbook pro drive over to the new computer, but adding this just in case it helps at all.

Please post your results with 115.3.0 which will ship in several days.
High processor use still occurs, pattern still seems similar: https://share.firefox.dev/3EUgOT2. Processor use hovering around ~125%
