191211 - Mozilla Hangs when sending email

Status: RESOLVED DUPLICATE of bug 169777

(MailNews Core :: Networking: SMTP, defect)

Description

[Eric Raymond]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.3a) Gecko/20021212
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.3a) Gecko/20021212

Mozilla uses close to 100% CPU (as measured by top) while trying to send a
message.  The message is not sent.  All of Mozilla is frozen (no redraws).

At one point I was getting this when trying to save a copy of the sent mail to
an IMAP folder, but I've since moved that to a local folder.  Didn't happen
every time.  It still happens sometimes.  Right now, it's happenening every time
 I try to send a message!  It wouldn't surprise me if the mail server is being
flaky in some way, but, IMHO, Mozilla should handle this gracefully.

I've seen this under Linux and Win98 with 1.3a.

Also, I'm not sure this is related, but I've seen general hanging (not crashing)
and instability when sending email and sometimes reading messages.  My guess is
that the there's some critical section of code which the mailer enters which
hangs all of mozilla. Perhaps this is related to flakiness of an IMAP or SMTP
server.  I realize this is not much to go on.  I wonder if mozilla should
display messages about server issues even when mozilla is retrying or thinks
they are transient?

Note: This appears very similar to what Albert Yang reported as a comment on 
http://bugzilla.mozilla.org/show_bug.cgi?id=112184#c22

Mozilla freezes when I try to send ANY email.  I assume it's this bug, but am
not sure.  It didn't do it before, but now it does, I've changed nothing on my
settings.  Using an IMAP connection; has worked for months, and now it's stopped
working.  It crashes so bad I don't know what to do except kill it in Task
Manager (Win2K).  I've upgraded to SP3 to see if that fixed it.  It didn't. 
I've downloaded last night's build to verify; it's still freezes.  I've tried it
on last night's build as of 11/27/2002 as well as Mozilla 1.2b, both crash.

Someone tell me how to dump the core on the crash or access the info from
talkback on such a bad crash, and I'll dump it out.  It's driving me nuts, I
might have to abandon Mozilla because of this....   I hope I don't.

Albert - sounds like your bug is unique - please file a new bug, and if you can,
post the contents of the IMAP log.  Instructions for generating this logfile can
be found here: http://www.mozilla.org/quality/mailnews/mail-troubleshoot.html#imap

Please note that a hang is not a crash (although it's obviously just as
serious).  This bug was intended for a specific crash only.  Albert, when you've
filed the new bug, please make sure I'm cc:ed on the bug.  Make sure you make a
comment in that bug when you file it, because my Bugzilla notification settings
are such that I won't see an email unless there is a comment associated with it.

Thanks!

Reporter:
Please close mozilla including quicklaunch and delete the file "xul.mfl" in your
Mozilla user-profile

Comment 2

[Andrew Hagen]

Reporter, can you disable copy to Sent folder? Then try to reproduce this
problem? Does the problem still happen?

Comment 3

[Eric Raymond]

The bug went away when I deleted xul.mfl.

Comment 4

[Andrew Hagen]

That's good to hear.

The underlying problem is likely to have been resolved in the latest trunk
builds. If you get this problem again using one of those, please report that to
bug 169777.

Duplicate.
