Version:           Unbekannt (using 4.2.90 (KDE 4.2.90 (KDE 4.3 Beta2)), Kubuntu packages)

I started kde 4.3 beta2 this morning, about 5 hours ago. Now after leaving the systm alone for some hours, akonadiserver runs at 100% CPU and a usage of over 4 hours CPU. Sorry, I did not copy that line of htop.

Now, after doing akonadictl start CPU usage is normal. But I get 83652 lines of mostly error messages (enabled all *akonadi* in kdebugdialog). This looks like the resolved bug 193249, but I have 4.3 beta2 which should have the fix I believe.

Most lines look like
