Thunderbird Freezing Consistently five minutes or more when using Teamup calendar (win10)
Hello, all.
Ever since I upgraded Thunderbird to 91.9.0 (64-bit), it has been freezing consistently and repeatedly - upon startup, and every 30 minutes, it freezes for approximately 5 minutes and 40 seconds. Then it unfreezes and works fine. But then 24 minutes and 20 seconds later, it freezes once again, going "Not Responding" in Windows 10.
When it freezes, Thunderbird uses 12-16% of my CPU, and memory usage steadily climbs, going up 0.1-0.2Mb each second, and goes back down to normal on the unfreeze.
Now, what have I done? It still happens in Troubleshooting mode. It happens in Troubleshooting mode while Windows is in Safe Mode With Networking. Adding an exception in my antivirus (NOD32) did nothing, as did turning off Allow Windows Search Messages in Advanced. Turning off Check For New Messages in Account settings does nothing. Nothing consistent shows up in the Error Console either, but I'm not a coder, so don't really know what to look for.
Ideas?
Thanks.

Oh yes, forgot to mention - have tried reinstalling and recreating the user profile. Nothing changed, freezing still happening.
The default update frequency for calendars is 30 minutes. Anything untoward in that area?
Two Google calendars linked with the googleapi, and one from Teamup.com linked with ics, which is read-only. They all seem to be working, but I'll adjust the refresh timing and we'll see if anything changes... :)
The upgrade has caused Thunderbird to freeze for me, too. When I try to check different email folders it won't budge, and I have to close and re-open the program for it to work again.
I've also run into freezing problems with Thunderbird beginning (I believe) with 91.8.1. This may not help you, but the solution for my machine was to disable hardware acceleration.

Well, I think you've got it. I increased the update frequency for the Teamup calender to 60 minutes, and the freezing did still happen, but then it took 54 minutes to freeze again. I set it to a Manual update, and apart from still freezing when Thunderbird starts up (it must do an initial sync), the freezing does not happen again.
So, it seems the calendar in Thunderbird does not like Teamup. Has that particular code been changed recently? And if not, could the fault be with Teamup? Where to go from here?
Have you tried toggling the offline setting. (in the calendar properties) I know it was problematical years ago. It might still be with that particular provider or calendar.
Is this a calendar with years of historical information that might be causing a long delay?
Otherwise.
Open the error console (crl+Shift+J), clear it and then synchronize the calendar. (right click menu)
Hopefully there is something regarding a teamup error or timeout than might shed light.
Nope, changing the Offline setting didn't make any difference. And I can see the GET command run on the .ics file in the error console, but there don't seem to be any errors that pop up either - but the error console seems to freeze too. Is there a way I can export the error log and post it?
