PS. Is this the best place to put bug/issue reports?  I believe this 
relates to the core image & kernel of a Jessie LTS release.

I'm seeing semi-regular spontaneous reboots on the BBB.  Here's what I'm 
seeing:

Running 'top', the "Mem Buffers" field, (4th line, far right), is steadily 
increasing until the system reboots at around (41180 buffers).

Anyhow, since I'm going after max stability, this is of concern to me, so 
I've been doing a little testing.

I'm not entirely sure what I'm looking for, but since I'm not running any 
of my own apps in this setup, I'm hoping the results might be useful for 
someone else?


I have logs available from

vmstat -s K -n 1 >> logfile

as well as a screengrab at time of fail of 

'top'

and

'slabtop'

Let me know if you have any insights or would like the logs.  I still have 
the image and am happy to run other tests if it'll help.  
In the meantime, I'm going to revert to a Wheezy console image and hope to 
find more stability there.

Best,
Dave

--------- setup is below

Setup:

Running from image:  RCN's jessie 8.4 console image of 4/7/2016  (with some 
packages removed, and a developer environment installed)

Kernel:  4.4.9 -bone-rt-r10 kernel

Running from SDCard

ssh'ed in via DCHP connected ethernet, most recently capturing vmstat to a 
log file.



PS.  Under a different testing scenario where I am running my own http 
server/app, I see strange behavior too.  I can say that my app has been 
extensively tested for leaks, etc, BUT can't rule out that it is my own app 
causing the issues when I am running it.   Nonetheless, maybe the 
strangeness will help dignose the above issue, so I'm including it here.

The strangeness I'm seeing is this:  There is a 24 hour recurring pattern 
to the reboots.    In the log below, I'm the number to the right of 
"Startup" is "seconds since last startup".

Any idea what this might be???  Logfile rotation?  Some kind of cron-job 
interference?
