Status: VERIFIED FIXED

Using 2000-03-14-05-nb1b mozilla build mac OS 9.0

I'm logging this bug because it happens to me all the time... refer to comments 
in bug #29908 from sfraser about "zombie thread on quit" bug, which he believed 
this to be last time I submitted a macsbug report for this problem.  He also 
mentioned there wasn't a bug report logged on the "zombie" problem -- now there 
is.

I've seen this in mar10 m15 build and mar14-05-nb1b1 build on mac.

Steps to reproduce:

1.  Launch to browser, open mail window.
2.  Login to IMAP account, open inbox, select a message and let it finish 
loading. 
3.  Close the mail window (I did so via close box).
4.  Back in browser... sometimes app is already hung now, click anywhere doesn't 
appear to register.  Otherwise, select Tasks|Mail. Notice nothing happens, mail 
window doesn't appear. Now application is hung.

This does indeed look like the 'zombie thread on quit' problem.

Pleeeease fix this... I'm hitting this pretty much every time I use Mac builds.
By the way, I included a mention of this in mailnews release notes.

Simon, do you think this is a Necko thread?  I looked at the stack crawl, but I 
didn't see anything that looked familiar.  Does this ever happen with POP 
accounts?

Comment 7

[laurel]

Yes, I see it happening with POP accounts, too.

My inbox hangs too at message 1820 out of 4000. I suspect it has something to do 
with a particular message it's trying to download. Not sure if it's the same 
problem, but I think mscott should investigate.

Comment 9

[lchiang]

I don't think it's the same problem.  Laurel doesn't have a problem with getting 
stuck downloading a particular message.  She gets beyond that.

bulk move to M16. Not an M15 stopper.  If you disagree, pls comment in bug and 
cc: [e-mail]

Comment 11

[selmer (gone)]

Not M16 stopper.  Marking M17.

[leger]

Putting on [nsbeta2+] radar.

Comment 13

[Scott MacGregor]

Laurel, is it safe to say you still see this problem?

Comment 14

[laurel]

Hmmm... I don't see it using a build from last week, maybe it's really gone (I
was seeing it so consistently for a long time).  Will try again when today's is
available. 

Comment 15

[laurel]

I can't get into this state over the last couple days using commercial build.
I'll check on a few other QA folks' machines, too. I'm hesitant to close it...

[David :Bienvenu]

danm fixed a zombie thread problem on 4/10 that would cause this. Did you ever 
see it after that? My guess is that this is fixed.

Comment 17

[laurel]

No still not seen. Guess we can call it fixed. Will mark it so and someone can
reopen it if they disagree.

Comment 18

[laurel]

Marking verified.
