Unclear whether this is related "mozilla::storage::Connection::shutdownAsyncThread" - putting it here for now

https://crash-stats.mozilla.org/report/index/aecccfb3-6dc4-40aa-b95a-85fcf0231020 "Operations such as opening and navigating through emails are slow. Sometimes it's early, but generally it's slow."

Turns out a significant percentage of crashes cite slowness - https://crash-stats.mozilla.org/signature/?proto_signature=~mozilla::TaskController::GetRunnableForMTTask&product=Thunderbird&signature=shutdownhang%20|%20mozilla::SpinEventLoopUntil%20|%20nsThread::Shutdown%20|%20mozilla::storage::Connection::shutdownAsyncThread&date=>=2023-04-29T00:00:00.000Z&date=<2023-10-29T23:59:00.000Z

#8 crash for 115.

Perhaps this can be correlated to another bug about slowness or hangs. There was a very strong increase in crashes with 115.3.1, but that might have just been from raising the update rate. In which case the problem could exist prior to 115.3.1.

User comments still mostly about slow opening, slow getting mail. For example

bp-dde654c3-4c19-4c6b-9d43-9c0800231025

I guess that storage thread is hang. When looking bp-fc44bc05-f8ae-4b9d-8a93-28f5a0231019, Gecko tries to close sqlite handle by CloseHandle. But this isn't finished. Other storage thread waits for it.

This may be hardware issue or 3rt party software issue such as anti-virus software.

There are some users with google drive and dropbox, but not in high percentage. Perhaps some of them have their Thunderbird profile on those services.

Also not seeing evidence of AV users in high percentage, although that would be unusual in the Windows world.

Sadly a few users with 115.0b6

crash rate is approx half compared to six months ago.
Over the last three months only a 15% decrease.

Comment 7

[Wayne Mery (:wsmwk)]

Crash rate is unchanged going from 128 to 140.
But it is no longer a topcrash.
