This is a known problem. See a previous email on the devel list about it

A bug is filed is at:
http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=545
For more info on the drop_caches mentioned in that gluster-devel thread,
see:

Do let us know if dropping caches as shown in that thread helps.
Dear Shehjar,
thank you, but drop_caches really is not the Holy Grail of this problem.
It simply does not change anything, to set it to something != 0.
Amon Ott figured it out, that forget() is called, but memory is not freed
anyway.
Of course, just doing drop_caches is not the silver bullet here. In some
cases, it needs to be preceded by a sync. What is your experience with that?
In any case, if Ott is right, then we might have a memory leak. The best
step is to file a bug.
Shehjar - I have sent the response to your private mail; sorry for that.
Syncing is IMHO irrelevant here, as there are no dirty buffers to be
written out to fs. The files are only opened, stated and closed.
I filed related bug report in ancient days, when the bug database was hosted on
savannah. If I remember correctly, it has been closed in the meantime.
Should I file a new report, or find the old one and reopen it (if it is closed)?
Krzysztof
We'll prefer having the old one re-opened if you can find it, if not,
feel free to file a new one.
