Description Andy 2011-12-21 03:54:42 UTC

Version:           4.7 (using KDE 4.7.3) 
OS:                Linux

I've been having a lot of problems with kmail2 ever since it upgraded to use akondai. I have about four disconnected IMAP accounts, one of which has approximately 42,300 saved emails spread across five different folders. For some reason this large account always gets hung and I can never open up my inbox. Whenever I go to click on the "inbox" folder, sometimes the icon will just spin forever and it will never come up. So I always have to close kmail and execute "akonadictl restart" in a terminal for it start working again.  

After upgrading to KDE 4.7.3 tonight, I can no longer access any of my mail (even after restarting akonadi), but now I can't even send mail. When I click on "Send Message", the windows darkens and then after a while it just pops up an error box that says:

> There were problems trying to queue the message for sending: Append failed

I should note that my "Sent" folder is in the large IMAP account that I can't open. When I look at the Akonadi Console, it just says that its status is "Online, Running 100%". I've tried clicking "Synchronize" and "Restart" a couple times over the course of several hours, but I still can't read my inbox or send any messages.

I'm not sure what the problem is because it was never sluggish or problematic with the old kmail. I had to disable the Nepomuk stuff too because that was just killing the machine for days.

Reproducible: Always

Steps to Reproduce:
Original Problem:
(1) Start Kmail
(2) Click on IMAP account's inbox
(3) Icon for clicked on inbox is spinning forever, no mail shows up

New Problem
(1) Click "New Message" to write a new email
(2) Click "Send Message"
(3) Application hangs and then displays the error "There were problems trying to queue the message for sending: Append failed"


Expected Results:  
I would like to read my mail and send new messages using kmail.

$ kmail --version
Qt: 4.7.4
KDE Development Platform: 4.7.3 (4.7.3)
KMail: 4.7.3

Comment 1 Andy 2011-12-21 20:13:42 UTC

I deleted the IMAP account and re-added it. The problem of not being able to load my inbox went away, but then I still couldn't send any messages.

After restarting (because akonadi_email_feeder was killing my CPU), I am back at the same problem. Restarting Akonadi from the command line eventually prints the following messages:

> posting retrieval request for item 82590  there are  1  queues and  0  items in mine 
> processing retrieval request for item 82590  parts: ("ENVELOPE")  of resource: "akonadi_imap_resource_6" 
> request for item 82590 still pending - waiting 
> continuing 
> request for item 82590 "503875" failed: "Unable to retrieve item from resource: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken." 
ItemRetrieverException :  Unable to retrieve item from resource: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.
> Error during executing query "UPDATE PimItemTable SET atime = :0 WHERE ( collectionId = :1 )" :  "Lock wait timeout exceeded; try restarting transaction QMYSQL3: Unable to execute statement" 
> Unable to update item access time 
> Error during executing query "UPDATE PimItemTable SET atime = :0 WHERE ( collectionId = :1 )" :  "Lock wait timeout exceeded; try restarting transaction QMYSQL3: Unable to execute statement"

The inbox still works in the old version of kmail.

Comment 2 Andy 2011-12-21 21:02:47 UTC

I just noticed that my emails are magically disappearing from my online Sent directory. I used the web-based version of my IMAP account and all the emails that I sent today from another machine running kmail 4.7.2 are gone. Not cool!

Comment 3 Massimiliano Torromeo 2012-01-03 10:55:09 UTC

I also have several problems with IMAP accounts with large amounts of emails and recently I have become unable to send emails and akonadi_imap_resource is always stuck trying to sync a folder.

Comment 4 Christopher Yeleighton 2012-02-13 15:27:30 UTC

I added my Gmail account to KMail and now it hangs on startup.
Process kmail uses 70% CPU.

The infinite loop probably starts at 

kdelibs-4.7.2/kdeui/itemviews/kselectionproxymodel.cpp:185

(it is hard to determine exactly because of optimization)

My back trace is due to Bug 294005.

Workaround: remove kmail2rc.

And after you are able to start KMail, configure it not to show favorite folders.
Create INBOX links in the Summary page instead.

Please reopen if you can still reproduce this in 4.13
