[Tracker] Excessive memory use by tracker-store

[Calvin Walton <calvin walton gmail com>]

Hi all,

As a bit of an experiment, after installing tracker 0.8.4, I decided to
try deleting all of its data files, journal, config, etc. in order to
see how a fresh install and index would run.

Admittedly I have a bit of a pathological case; my home directory has
approximately 2.7 TiB of data, including both a collection of large
media files (video and music) mixed with small development files (git
clones of a large portion of gnome, the linux kernel, etc.)

I've left the indexer processes running for about 24 hours now, and it
has reached 83% complete. But I'm a bit worried about the memory usage:

In the GNOME System Monitor, tracker-store is currently reported as
using 9.9 GB of memory.
The memory use has been steadily increasing with time; several hours ago
(at around 60-70%) it was at about 5 GB of memory.

There was also increased memory usage in gvfsd while this was occurring;
it hit ~4.5 GB a while back, but has recovered to ~300MB since.

My system's not unusable yet, due to having excessive amounts of both
ram and swap, but needless to say, I'm a little concerned.

Any ideas about why this could be? If you want me to try some debugging
or profiling work, I'd appreciate some pointers on where to start.

I'm willing to rerun this with changes as needed. (It's just a personal
box, and I don't have any important info stored in tracker... yet.)
