Description Luis Silva 2011-09-18 16:10:21 UTC 
Version:           4.8 (using KDE 4.7.1) 
OS:                Linux

The akonadi_imap_resource takes a long time (a minute or more for my gmail account) to shutdown. Staring akonadi from a terminal and then stoping it shows that the imap_resources are crashig on exit. This seems to have no effects on my data bu delays kde on logout or shutdown.

Reproducible: Always

Steps to Reproduce:
Just open a terminal and do:
akonadictl stop

Keep monitoring the akonadi processes with your favorite tool and verify that the imap_resources take ages to dispear after all other resources are already <defunct>.


Expected Results:  
The imap_resource should take only a few seconds to shutdown as other resources do.
Comment 1 David Faure 2012-01-05 11:34:46 UTC 
Can you post a backtrace of akonadi_imap_resource?
Comment 2 Luis Silva 2012-01-06 11:23:12 UTC 
I can, if you tell me how to do that. I couldn't find a way to do it manually and I am not getting any crash dialog I can follow.

Comment 5 Luis Silva 2012-12-26 18:09:14 UTC 
This problem is still present in master. I cannot find a way to produce a crash report or even a backtrace from this crash but I alwasy get the following message when akonadi closes:

QProcess: Destroyed while process is still running.
ProcessControl: Application /usr/bin/akonadi_imap_resource stopped unexpectedly ( "Process crashed" )
Application '/usr/bin/akonadi_imap_resource' crashed. No restart!
Comment 6 Kevin Ottens 2013-11-16 07:32:32 UTC 
The IMAP resource has a new maintainer, reassigning to him.
Comment 7 Christian Mollekopf 2013-11-19 16:20:02 UTC 
Does this still apply to 4.11.3>=?
If it does we need a fresh backtrace.
Comment 8 Christian Mollekopf 2013-11-19 16:20:10 UTC

Comment 9 Luis Silva 2015-10-11 12:06:57 UTC 
This does not happen any more.
