Default Nepomuk loses its memory after session restart

I've just had the unfavorable experience that nepomuk has apparently
lost its memory after indexing 75.000 files. All I had to do was to
logout from the session and then start a new one. As nepomukservices had
bloated to 2GB of VM, I thought this a good idea.

In order to check whether only the full-text index is affected, I set
the rating and comment on a file and again restarted the session. Alas,
both were lost afterwards.

Am I having particularly bad luck here or are others seeing similar
things?

Michael

Others are seeing similar things: https://bugs.kde.org/show_bug.cgi?id=226895

See also the "Strigi is always indexing" and "Desktop search: should background processes be
(io)niced" (and "Need for help in patching and packaging kdebase") threads.

This is likely to be the recent virtuoso borkage [1][2]. In other words, make
sure you have fully upgraded virtuoso-minimal and its dependencies to version
6.1.0+dfsg2-3. Then either:

1) disable desktop search, killall nepomukservicestub and virtuoso-t (if they
remain), wipe out nepomuk database (rm -rf
~/.kde/share/apps/nepomuk/repository/), and reenable desktop search letting
nepomuk to reindex everything again;
2) log off from KDE, rm -rf ~/.kde/share/apps/nepomuk/repository/ from virtual
linux console, relogin, let nepomuk to reindex everything again.

In either case, make sure nepomuk search in dolphin works. Sorry, but there is
no reliable to fix this without nuking nepomuk virtuoso dabatase.

This is exactely the bug I was helping to fix in the past days. Prabably
it will be gone for 4.4.2.

Yes, apparently that's the case. I saw the notice when upgrading, but
interpreted as 686 not being affected. Well, it was.

Seems to work fine for now. I'm getting used to deleting the nepomuk and
akonadi backing stores.
