509001 - Message headers keep being downloaded again for IMAP account

Status: RESOLVED INCOMPLETE

(Thunderbird :: Folder and Message Lists, defect)

Description

[Chris Rodgers]

User-Agent:       Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.0; WOW64; Trident/4.0; MathPlayer 2.10b; SLCC1; .NET CLR 2.0.50727; InfoPath.2; .NET CLR 1.1.4322; .NET CLR 3.5.21022; .NET CLR 3.5.30729; .NET CLR 3.0.30729)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-GB; rv:1.9.1.1) Gecko/20090715 Thunderbird/3.0b3

I have three IMAP accounts. Two work fine, but for the other, Thunderbird often "forgets" the message headers. This means that when you go back to a folder, it takes a few seconds (sometimes longer) to download all the message headers again.

This has happened since I moved to v3 alpha.

Reproducible: Sometimes

Steps to Reproduce:
1. Start Thunderbird.
2. Read messages in a folder e.g. Sent.
3. Switch to another folder.
4. Move back
Actual Results:  
Now you have to WAIT some time whilst all the message headers download.

Expected Results:  
It should be very quick - nothing has changed on the server.

Can you get an IMAP protocol log for that 3rd account?
