The first thing to do is to register the Kindle.
Is this a "Special Offers" (ad supported) Kindle?
Code:
170706:152555 cvm[4489]: I DownloadHandler:CampaignLifeCycle:timestamp=1499354755842:start handling merchant todo item
170706:152555 cvm[4489]: W DownloadHandler:Warning::Device not registered, decline merchant update request
First column: YYMMDD:HHMMSS
Second: Task name: cvm Task ID 4489 - cvm is the Java virtual machine that executes everything Java in the system.
There is probably more things to find.
When either I get more time or someone else gets more time.
There was also an unusual amount of uploading going on, and to a location I do not recognize as part of Amazon.
That will take some research time (best done by someone running 5.8.9.2 - not I).
(Congratulations! You may be running the
first documented, Kindle-Bot.) *
If your Wifi router has the ability to log connection destination IP and/or name - -
Turn that feature on - we may need those logs if this is indeed a "Bot" running.
And while we are thinking about this, you be thinking of how you can run WireShark on the connection (that depends on how you have your networking equipment set-up).
* There have been other reports of Kindles that restart by themselves frequently, but this is the first attempt at documenting what is happening.
