I've noticed what appears to be a memory leak using the TS-7200. 
We're using the as-delivered factory configuration, which includes
kernel 2.4.26-ts11.

I've submitted this question to Technologics support and haven't heard
back yet.  Perhaps someone on this group has seen this problem?

If I boot the board using root=/dev/hda1 (i.e. boot from the
Debian-based rootfs on the included CF card), the system loses about
4KB every 2-5 hours.  I've seen this on an idle board with ethernet
configured but cable disconnected, interacting via the serial console
and running the following bash command:

ts7200:~ # while true; do date; free; sleep 3600; done

Here's a summary of the free command output at 0 hours and 46 hours
into the test:

         used    free     buf  cached
0 hrs   15568   13304     788    8788
46hrs   25004    3568    2500   10112

You'll notice that buffer/cache allocations increase, but not nearly
enough to account for the decrease in free memory.

ps listings taken at 0 and 46 hours show no appreciable change to the
memory allocations for processes.

This problem is not duplicable when booted into the rootfs on onboard
flash (root=/dev/mtdblock1).  Used memory is unchanged over a 48 hour
period.

I'm interested if anyone has seen this problem and/or has a solution.

All the best,
Steve
