           Summary: akonadi eats my memory ;)
           Product: Akonadi
           Version: unspecified
          Platform: Archlinux Packages
        OS/Version: Linux
            Status: NEW
          Severity: major
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: cullmann at kde.org


Version:           unspecified (using KDE 4.6.5) 
OS:                Linux

I have configured KMail from KDE 4.6.5 to connect to my IMAP account.
The account contains > 400k mails, in short: a lot ;)
Now, even if I don't start KMail after logging in, akonadi starts up and eats
my memory (and sometimes my CPU).

I have 4 GB of memory and no swap, got OOM'd just now without any applications
open beside one chrome + amarok.

once it killed akonadi:
[ 2563.614023] Killed process 1728 (akonadi_nepomuk) total-vm:632676kB,
anon-rss:224724kB, file-rss:4kB

later chrome (which did not take lot RAM)
[ 6020.429589] Killed process 1736 (chromium) total-vm:931484kB,
anon-rss:90960kB, file-rss:7036kB

Even now, after some OOM'd doom, I have running:

File indexing is off (nepomuk itself, too, in system settings, still it is
launched)

I know, I have a LOT of mails, but why does it seems to that the akonadi
storage tries to download it behind my back and index or whatever it?
Have not activated any offline features.

Reproducible: Sometimes

Steps to Reproduce:
Starting up my KDE session after having configured the IMAP account. Without
any configured IMAP account, all is fine (which is no real suprise, as then
nothing is there to leech ;)

Actual Results:  
OOM session or hanging session cause of load.

Expected Results:  
Akonadi should be off without KMail starting (but perhaps that is the panel
clock or such stuff, not that there is an option), but in any case, even if
KMail is started, it should not use that much real memory. With the "old" KMail
from KDE 4.6.4 it was just fine, no real memory usage that bothered me.

This is plain ArchLinux packages, 4.6.5, not testing, no own compiles/changes.
Settings were plain new, installed this machine fresh with this KDE version
(and cleaned .kde and .local stuff)

Major, because that OOM's randomly my other apps. (which doesn't only include
poor old SC2 ;)
