Hello Len,
You should run as root to get propper realtime priorities.
You can reduce the memory usage at runtime, please have a look at
executable -u and look for stacksize
Generally I have to say that EtherCOS is still in alpha state. I am
working on a new release working on XCos and Scicos but there is much
work to do. The problem is that I work on this project in my free time
(conflicts with family and busy job). So there is a lack of time. If you
want to do further work on it feel free to do this and yes there is a
repository. If you like I can grant you access rights
Greatings

Hi all,
Just to inform anyone working with ethercos (are there any?)
If you are trying to run an ethercos generated code application
without root privileges, you may run into a segmentation fault, caused
by a memory allocation problem. Running as root avoids this problem.
If you want to be able to run as user joe anyway, run "ulimit --l"
and/or check /etc/security/limits.conf.
The ethercos runtime locks a lot of memory, and some distributions
(like Debian Lenny) limit this for normal users.
If you change /etc/security/limits.conf such that memlock is something
like 32768 (a number that works for me) this problem is over.
Cheers,
Len.
