So, I just noticed that after I boot Angstrom on BBB, the available memory
listed for the rootfs drops steadily...
I'm not running any apps or doing anything, except SSH session and
periodically doing 'df'.
I disconnected eth0 and there is no wireless dongle.
Eventually the 'free' value reaches zero. I do recall that the when I
updated the eMMC, the reported free was about 50MB. I installed a bunch of
node.js libs, but it only got to about 20MB.
But, I just noticed that the free value was decreased while I basically did
nothing. I suppose something could be logging bunch of errors somewhere.
Anyone else notice anything like this?
