--- Comment #14 from dave@jetcafe.org ---
So I only wrote the script for the purposes of addressing comment 11. My main
source of data is said sysctls exported at intervals to prometheus, which is
where I get the graph you can look at in the attachments here. 

That being said, if stopping and restarting services released the lost memory
due to lazy reporting, it should have shown up in prometheus eventually. It has
not for the past few hours. 

Additionally, bug #234559 seems to be a reporting issue. If that were only the
case, I would not have opened this bug. :) If you read the original comment, a
machine with this bug left to itself for long enough will start swapping, then
thrashing, and finally panic when the swap space is exhausted.
