1581849 - Thunderbird Daemon lives after closing - Spawns many instances... causing very sluggish response (eats up memory eventually)

Status: RESOLVED INCOMPLETE

(Thunderbird :: OS Integration, defect)

Description

[John McDonnell]

User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3895.5 Safari/537.36 OPR/65.0.3443.0 (Edition developer)

Steps to reproduce:

1.) Open Thunderbird
2.) Close It using the X SYMBOL (TOP RIGHT) - (Using File > Close terminates the Daemon Properly)
3.) Open Thunderbird Again
4.) Close Using X SYMBOL (TOP RIGHT)
Repeat as needed.

Actual results:

Application daemon remains live using the X symbol and after many days if not weeks it's very easy for this to bring a system to it's knees resource wise as the daemons continue spawning as new instances. If you select file close the daemon terminates properly - it's only when utilizing the graphical X. Once you kill the initial daemon you will get a series of graphic closing errors equal in the amount of instances open.

Expected results:

The program daemons should terminate? Unless this was by design to bg/fg but since this is a X11 based version - no real command line integration I'm guessing this a defect.

Attachment: Close thunderbird

This Error Spawns AFTER CLOSING - unlike past errors I can open and close without issue... I can only generate this after running the kill command on the residual daemons that are backlogged... after killing one the entire que crashes and throws this error for each and every daemon in the background that was still in existence

Attachment: Just a sample of reproduction test - open and close four times.

We've seen other reports of this on linux - both on shutdown and startup - and none of them caused by Thunderbird iirc.

for some reason this query https://mzl.la/350xkxI is messed up, but looking at the "invalid" bugs in https://mzl.la/2NlHUK2yields
Bug 1559857 - Thunderbird 68b1 infinite loop (100% cpu usage) and hanging on startup
Bug 891314 - Thuderbird starts many processes under Linux

See also Bug 1585695 which seems a similar issue on Windows.

John, which full version number did this start?

John ?

FYI as per Jork confirmation in 1585695 comment 3 it seems the issue is by design:

"...
File > Exit will close all windows. Clicking the [X] on the main window will not close the application and will leave non-modal windows open, most prominently the compose window.
..."

Personally, as I reported in Bug 1585695 and John here, I would expect inuitively that pressing [X] at the top right corner of main TB window would have the same effect than File > Exit... to close TB and all related processes/remaining windows at once.
