Some of the processes don't hang it seems (the akonadi_ical_resource didn't, the akonotes and maildir ones did)

The same here. It doesn't have to be KDE logout, it is sufficient to run:
akonadictl stop

Forgot about software versions:
akonadi 1.4.95
KDE 4.5.95
KDE PIM (for some reason in Arch it is in a different version?): 4.5.94

Same here..very annoying..
akonadi 1.5.0
KDE 4.5.95
KDE PIM (for some reason in Arch it is in a different version?): 4.5.94
(the last beta release I think)

Some other input...I start kde with startx (exec ck-launch-session startkde in .xinitrc)
logout hangs 10-15 seconds until akonadi_agent crash and exit

just a question: are the reporters here all using archlinux?

I'll add QT version 4.7.1 as seems mentioned in the crash

No. I'm a LFS user.

I'm still seeing this issue with:

Reproducible: Always

Steps to Reproduce:
1. start akonadiserver.
2. restart it if you can't reproduce with the first step.

*** Bug 265049 has been marked as a duplicate of this bug. ***

bump , this is so annoying... any word from a dev here?

Since nothing's happening here... let's try to narrow it down a bit.

To me, it seems this is related to the akonadi resources from the kdepim(-runtime) 4.6 beta/rc packages. I.e. I don't have any issues with akonadi on *any* of my systems that still uses kdepim-4.4. On the other hand, I'm seeing it on *all* systems with kdepim 4.6beta/rc. Same akonadi version on all systems.

Specifically, the two resources I'm having issues with is the "notes" resource, and the "imap" resource.

The notes resource will trigger a long delay when shutting down akonadi (with akonadictl stop), before finally crashing. When this happens, I see this in akonadi's console output: "QProcess: Destroyed while process is still running"

Removing all "notes" resources completely fixes the issue for me on the systems where I don't have any imap resources.

For imap, there doesn't appear to be any issues if stopping akonadi *before* connecting to the imap servers. For example, when stopping akonadi before starting kmail. If a connection has been established, the imap resource is *always* causing a delay when stopping akonadi (and then crashes).

Furthermore, it's always the *same* imap account (I have multiple imap accounts on all my systems). Not sure if it's something specific to the account, or if it's because it's not the first imap resource (i.e. the problematic account has the highest resource number on all systems).

Is there anyone having issues with *other* resources? Or are these the only two? Anything else that can help narrow this down will help...

Btw, current versions:

QT 4.7.2
KDE 4.6.2
Akonadi 1.5.2
PIM 4.5.94.1, and latest git (2011-04-09)

Yet some more info... even though I remove all problematic resources (and thus making akonadi stop without any delays), logging out from KDE still takes a long time.

This turns out to be akonadi not being shutdown automatically when logging out. Instead, ksmserver waits until it hits it's timeout, which I believe is 10s, before continuing shutting down KDE.

It shutdowns fast again if I manually stop akonadi before logging out. But this (including scripting and adding shortcuts to the desktop or similar) is only a temporary workaround.

Note that adding a script to $HOME/.kde/shutdown doesn't help, since those scripts are executed *after* logging out from KDE, while akonadi needs to be stopped *before*.

the imap resource doesn't use the akonadi_launcher_agent afaik

(In reply to comment #13)
> the imap resource doesn't use the akonadi_launcher_agent afaik

Hmm, yes, you're right. So it may be a completely different problem. Or it may not, as it's still related to stopping akonadi.

Looks fixed for me, I don't see new coredumps when restarting the server.

Does anyone still see these crashes with Akonadi 1.5.2 and kdepim >= 4.6beta5 ?

Working fine now indeed.

Yes, I do.

"akonadictl stop" now stops all resources immediately, but there's still a crash (visible in dmesg).

Furthermore, I still have the, related or not, problem with akonadi delaying logout from KDE, *if* I have unconnected imap resources. If I at some point during the session started kmail, logging out is not delayed by akonadi, regardless of whether kmail is still running or not.

kdepimlibs 4.6.2
kdepim{-runtime} 4.6beta5

what does akonadictl --version return ?

Probably related: if I start (and quit) kmail before running "akonadictl stop",
then I *don't* see any segfaults.(In reply to comment #18)

> what does akonadictl --version return ?

akonadictl --version
Akonadi 1.5.2 (revision: 4997976)

Still seeing the exact same problems with 4.6rc1; akonadi agent launcher segfaults, log-out hangs for ~30s if imap (that never connected, i.e. kmail was never started) resources exists.

akonadi-1.5.3
kde-*-4.6.3
kdepim-4.6rc1
kdepim-runtime-4.6rc1

Problems still present in kdepim-4.6rc2.

still happens with kde 4.6.80 and akonadi-1.5.80

Problems still there in kde 4.6.4, akonadi 1.5.3 and kdepim-4.6.0

This also happens to me on archlinux x86_64, with kde 4.6.4, akonadi 1.5.3, kdepim 4.6. What's interesting is that it happens on a new user account too, with no imap or any other resource configured.

...also, if an email has been sent (outgoing mail is sent through smtp and is also stored on "sent" local folder) since it's last restart, akonadi exits properly and kde is logging out instantly.

no news here? bug still present in last versions of kde rc and akonadi :(

same here on Gentoo

Akonadi 1.5.3
QT 4.7.3
KDE 4.6.4 (libs)

Same here on arch x86_64, KDE 4.6.5, akonadi 1.5.3

Same here on arch x86, KDE 4.6.5, akonadi 1.5.3. It crashes here :

) at /BUILD/ARCH/akonadi/src/akonadi-1.5.3/agentserver/agentlauncher.cpp:28

Here's what I see with KDE (incl. PIM) 4.7 rc2 and akonadi-1.6.0:

* No more segfaults, at least not in the logs
* Logging out no longer pauses for ~30s, regardless of the state of my imap resources.
* Akonadi stops (akonadictl stop) instantaneously *if* the imap-resources hasn't connected to the imap-servers.
* Akonadi does *not* stop immediately (~10-30s delay) if the imap-resources has connected.

Note that in the last case, the akonadi log output says the imap resource process crashed, but there's no segfault logged to syslog.

The KDE version doesn't matter much for this report. For the people still seeing this crash, please report :
- the Akonadi server version (using 'akonadictl --version')
- the KDEPIM version (using eg 'kontact --version |grep Kontact')

As already commented and confirmed in comment #16 and #30, we don't see this crash with recent versions (Even with 11 resources using the agent_launcher, I don't see anything here).

I see this with Akonadi 1.6.0 and kdepim 4.6.1. Note that the akonadi_agent_launcher proccess that crashes is the one associated with akonadi_maildir_resource.

Akonadi 1.6.0
kdepim 4.6.95
Kontact: 4.7 rc2

Here's a log from startx with the crash in the end
http://pastebin.com/0JcCAprE
I start the session, open kontact, and close session. The logout took at least 10-15 sec probably due to akonadi-launcher crash or try to restart.
In the syslog I see also this:
13/7/2011 14:01:03	localhost	kernel	[  517.604838] akonadi_agent_l[7767]: segfault at 7f86e7a7c190 ip 00007f86f26ff418 sp 00007fff51c455a8 error 4 in libQtGui.so.4.7.3[7f86f2336000+a37000]

I never use kdm, I always start KDE from startx, ending in a console when I'm done and logout.
Hope this help

After adding a new imap resource, the akonadi_agent_launcher crashes are back, and so is the delay when logging out.

akonadi-1.6.0
kdepim-4.6.95

I don't use imap but I get many crashes (KDE 4.7rc2 with Akonadi 1.6.0) :

Fixed for me.

Can anyone else test master or 1.6 branch ?

seems to work here too.
test performed: fresh start , opened kmail , done some stuff , logout.
Shutdown is now very quick and the crash is gone.
Thank you, thank you very much indeed , this one was so old and annoying!

Same here. Closing then.

Tried a few akonadictl stop/start + logouts here too, and it does indeed seems to be fixed; no crashes, and logout is finally fast again.

Will try this as soon as possible on my remaining two systems.
