On my Wheezy system, I've noticed that for the past 2 or 3 days, gvfsd-
metadata has been the top running task when I check with top.
Comments:
* I've never seen that before (I've never even noticed that I had such as
task running (I didn't look for it, but I didn't see it)
* I did a little googling to see what it is / does, it seems to have
something to do (didn't read thoroughly or completely) to do with file access,
maybe starting with GNOME based files, but maybe also other files.
* I'm running Wheezy (Debian 7.n, up-to-date (as of when Wheezy stopped
being updated), with KDE (3.n), and I'm not ready to give up the version of
kmail there (which does not use Akonadi (sp?). (I am aware of the Trinity
system that continues to support KDE 3.n, and, if I have to give up on Debian,
I would install Trinity on this system).
* Almost always, when I check top, firefox-esr (sometimes without the esr,
iirc) or Web Content are the top two tasks.
* A few days ago, firefox was running very slow (too many tabs open) so I
restarted firefox. I can't say for sure that gvfsd-metadata started being the
top running task after I did that (because I didn't check immediately), but I
can say that wasn't the top task before I restarted firefox.
* Before the restart mentioned above, either Web Content (or firefox-esr)
was using 13 GB of space and often hit 100% CPU (on this two core system).
Firefox is working better since the restart, and I can't say that I notice any
real problems at this time, firefox might be a little slower than before the
restart.
I'm looking for comments -- should I be concerned about this? Should I do
anything about it?
I suspect that stopping gvfsd would be a mistake (well, unless I restarted
it). I do have thoughts about rebooting the system, maybe it is time to clear
out some cruft (of whatever sort)?
Comments?
Thanks!

It sure looks like a bug of some sort. "gvfsd-metadata" process in
"top" on my system (Buster) is always idle:
