           Summary: akoandi-nepomuk eats all CPU shortly after login
                    ($HOME on NFS) for about 2 minutes
           Product: Akonadi
           Version: 4.5
          Platform: openSUSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: Nepomuk Feeder Agents
        AssignedTo: tokoe at kde.org
        ReportedBy: t.kleindienst at web.de
                CC: vkrause at kde.org, kdepim-bugs at kde.org


Version:           4.5 (using KDE 4.5.1) 
OS:                Linux

I have about 10000 emails in my inbox and about 8000 in the sent-mail folder.
All email-folders consume about 5.1 Gb.
After login akonadi-nepomuk eats all the CPU and the system gets unresponsive
for about 2 minutes. System is OpenSuse 11.3 with decent hardware Intel Core
i5, 4x3.33Ghz, 4Gb Ram.
$Home is located on NFS, 100Mbit wired.

I understand that this process is needed to feed the akonadi-data into nepomuk.
What I don't understand is, that I still use 4.4 kontact, thus akonadi is not
handling the emails. What actually does akonadi-nepomuk?

Can this process run with a lower priority? Or can the load be reduced by
limiting the CPU consumption? I would not mind if it takes 5 or 10 minutes to
run, but unobtrusive in the background.


Reproducible: Always

Steps to Reproduce:
Simply log in and watch CPU-consumption going up.
