</I>It's the database backend for Nepomuk, and i assume that it does the
initial indexing of your /home. It does not leak memory, and it's not really
needed,
you might want to disable Nepomuk/Strigi altogether.
You might want to look at

</I>><i> taking 36MB and plasma 12MB...
</I>><i>
</I>><i> after killing it, in less than 10min, it's back up there using already 100MB
</I>><i> and 75% CPU of a core.
</I>><i>
</I>><i> on such a mostly idle VM, i don't see the benefit...
</I>><i>
</I>><i> i note that it doesn't always use 75% CPU, sometimes it doesn't use any CPU,
</I>><i> but the next minute it's back to use 75% .
</I>><i>
</I>><i> just wondering if there's a good reason for this?
