Hmm, hard to say, what exactely is the reason for your problems. The stack is well known for having several problems regarding mbufs and others...but I thought, the commercial eCosPro Version, you are using, should contain an improved stack version!
One of our porting projects was for Atmel AT91SAM9G45 and our customer Softing provided a bunch of improvements. You could compare your version with our version, available at http://tiprom.itrgmbh.com/projects/ecos-on-atmel9g45 Maybe it's helpful!
