Hi all -
I have a data logging JamVM application on ts-7260 boards running Debian from
an SD card. In some of my applications configurations, I find that the Buffers
value obtained from `free` rises, then falls to zero over the course of about
six hours. Once Buffers hits zero, the boards become unreachable, and all
application processes appear to hang until a power cycle.
In other configurations, the Buffers value rises and stays above the Free
value, following a sawtooth pattern. On these boards, all remains OK for long
periods. Occasionally I've seen these boards suddently exhibit a similar
memory pattern, with Buffers suddenly declining until reaching zero, and again
these boards become unreachable.
I'm at a loss to understand what is happening. Have experimented with swap
files, new versions of JamVM, code modifications and some sysctl settings,
examined netstat, lsof output, all without any improvements.
Has anyone every seen anything like this, or have any suggestions for solving
this problem?
Thanks!
