228859 - LDAP SSL connection not closed on thunderbird shutdown

Status: RESOLVED DUPLICATE of bug 206018

(MailNews Core :: LDAP Integration, defect)

Description

[Ronny Adsetts]

User-Agent:       Mozilla/5.0 (Windows; U; WinNT4.0; en-US; rv:1.6b) Gecko/20031208 Firebird/0.7+
Build Identifier: Mozilla Thunderbird 0.4 (20031205)

After using Thunderbird with an IMAP SSL connection, it does not close cleanly
producing an error dialogue on application shutdown.

Reproducible: Sometimes

Steps to Reproduce:
1. Open Thunderbird with an SSL IMAP server setup
2. Send an email
3. Close Thunderbird

Actual Results:  
Error dialogue appears (screenshot to be attached).

Expected Results:  
The shutdown should complete without error.

I generally keep thunderbird open for long periods of time. I have not managed
to reproduce the problem by opening thunderbird and trying various things then
closing. NOTE: I just managed to reproduce by sending an email only as above. In
case it makes a difference, I have an LDAP directory configured.

Server is Courier IMAP SSL v1.7.3 built against openssl v0.9.6c (with security
patches - Debian Woody).

Workstation in WinNT v4 SP6a.

are you saying that this only happens sometimes? Is it possible that it's an
ldap connection that hasn't been cleaned up? Do you have autocomplete against
the ldap server setup? Have you tried just bringing up the address book and
doing a query on the ldap server and then shutting down? I have a vague
recollection of hearing about this problem with LDAP - however, it's odd because
our LDAP code doesn't cache connections (though maybe the underlying LDAP SDK
does, but I doubt it). We shutdown all our imap connections when the app is closed.

You are correct, it is LDAP. Turned off SSL on the LDAP connection makes the
problem go away.

I do have autocomplete on LDAP turned on.

It happens reliably. With LDAP SSL turned on:

1. open thunderbird
2. new message
3. enter a name for auto-complete in the To box
4. close and discard the email
5. close thunderbird

This will produce the error dialogue as previously attachted.

Server is OpenLDAP v2.0.27 built against OpenSSL v0.9.6c.
