Anything is stopped inclusive akonadi.

Installed now and start of akonadiconsole did also start akonadi itself. 
However, since the two phantom IMAP resources were no longer able to 
synchronize themselves. I stopped anything again, took a backup of the 
akonadi configuration files and mysql db and start from scratch.

After starting KMail, the IMAP resource was working again. However, it was 
not the KMail process itself that took my memory but the 
akonadi_imap_resource. It went up to 3.2GB stayed there for some minutes but 
went then down again to 1.1GB.

Then I stopped Kmail and restarted it again. This time I got the "old" 
behavior: The KMail process consumed memory up-to 4.1GB and the process 
crashed then.

I cleared the tabs before starting KMail again, but that can be provided. 
Where should I put it? I already attached a stack trace to bug 294447.

BTW, while I was writing this message in KNode, suddenly the 
akonadi_nepomuk_email_feeder starts to gather memory with a peek also at 
4.1GB, but went then down again to 2.0GB - where it stays.

Nothing special - at least not for me.

Undone.

Thanks for your time,
