Publishing stops after a while (in embedded)

[vmayoral]

https://github.com/ros2/ros2_embedded_nuttx/blob/master/apps/examples/ddsimu/main.c starts publishing as soon as the other is discovered and eventually (after publishing for a while) stops.

The embedded board has still the other peer marked as discovered (checked with the !!sdisc command) however it just stops publishing. It sounds to me like a buffer issue.

The embedded board seems to be running out of memory:
