502558 - Shutdown fails with 100% cpu load when auto-complete over LDAP is used

Status: RESOLVED DUPLICATE of bug 420744

(MailNews Core :: Address Book, defect)

Description

[Henrik Skupin [:whimboo][⌚️UTC+2]]

Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.1.1pre) Gecko/20090705 Shredder/3.0b3pre ID:20090705024443

Since a couple of days I have noticed that when trying to upgrade Shredder the shutdown doesn't work. It hangs and the following alert is shown:

"The operation cannot be completed because of an internal failure. A secure network connection has not been cleaned up correctly."

Eventually this has been started since I have been using my StartCom free SMIME certificate.

Are you using an SSL LDAP server and doing auto-complete against it? This sounds like a dup of the bug where we don't always clean up ldap connections. Or could it be the ssl update connection isn't cleaned up?

Comment 2

[Henrik Skupin [:whimboo][⌚️UTC+2]]

Yes, I'm using the Mozilla LDAP server with auto-complete turned on. I haven't seen it the last time though.

Comment 3

[David :Bienvenu]

If you shutdown immediately after sending a message with auto-complete, you can encounter a known bug where we haven't cleaned up our ssl ldap connection before shutdown happens. Is it possible this is what happened to you? I can't find the bug right now, but if so, it would be a dup of that bug, and not a blocker.

Yeah. That's it. When you find the bug feel free to dupe. Thanks David.

henrik, please check to see which tcp connections are open - ldap or imap. I doubt it's ldap - I think those bugs are all closed. [1] eg Bug 396364 -  Address Book fails to shut down correctly if LDAP password dialog is cancelled

It's definitely auto-complete. When I use an already sent email and send it again without using auto-complete the application shutdown without any problem. Only when using auto-complete which is a LDAP connection for mozilla.org causes this hang. If no other bug is open we should track the issue here.

I'm sure we had a bug on this - I don't know if it was marked fixed or not. We did make several fixes for leaks of ldap connections, but this is more of a shutdown race, caused by difficulties in cleaning up the ldap connections.

yeah, I forgot to comment/agree that we had seen this in the past, and jives with a bug comment of mine implicating compose/autocomplete which I can't find (bonus if you find it).  Am having @)#$(* trouble finding it because it probably doesn't have ldap in the summary or component :)  I don't know if this list nails it but here's what I come up with ...

open Bug 420744 thunderbird hangs on shutdown 
INCO bug 482094 Thunderbird failing to close properly  (which I recently closed - no opinion on whether we should reopen)

recent FIXED bugs include
 Bug 382446 -  Alert on shutdown when using ldaps address book - "operation can not be completed because of an internal failure. A secure network communication has not been cleaned up correctly."
 Bug 396364 -  Address Book fails to shut down correctly if LDAP password dialog is cancelled

there's Bug 494014 - shutdown hang, high cpu, no open imap connections - but iirc that's not ldap related

There are open and incomplete shutdown bugs which are not well defined, eg bug 482094.

xref last comments in FIXED bug 487965 - hang on shutdown with open imap connections and zero cpu

Comment 9

[David :Bienvenu]

bug 382446 was the one I was thinking of - it was marked fixed because the main connection leak was fixed, but afterwards, we discovered that there's still a connection left open if you shut down immediately after sending a message. I think this bug can stand for the remaining issue, because I can't find a bug that describes the issue - davida ran into it, and we (Standard8 and I) debugged it, but I don't know if the info ended up in a bug.

OK found my comment - bug 420744 comment 2 and comment 5 and stephend's  bug 420744 comment 6 (I was an idiot for not putting ldap in the summary)

duping to bug 420744 which has several ppl already cc on the issue
