@preed
Thank you again. I will look into an industrial SD card.
Before posting here I spent several days reading the Fast-RTPS code and running valgrind's Massif tool on the sample applications. I was not able to find anything that could be easily reduced or eliminated.
It seems to me that the code is memory intensive as it is implemented and intended to run on systems with several gigs of RAM and plenty of swap space.
I hoped someone here could tell me that I was wrong and that there was a network buffer size or something else that I could configure to be smaller.
nn.
