AFAIK, bind() should never return EAGAIN for an error:
http://homepages.cwi.nl/~aeb/linux/man2html/man2/bind.2.html

but it does in eCos...anyone know why?

thanks,

ken

Hi Ken,

In the BSD manpages, EAGAIN means, you are out of memory, see for instance:
http://www.unix.com/man-page/FreeBSD/2/bind/

There is a configurable memory pool for variable size objects in the bsd stack.

I'd suggest you should increase CYGPKG_NET_MEMPOOL_SIZE

and check that too:
CYGSEM_MEMALLOC_ALLOCATOR_VARIABLE_COALESCE should be 1 (default)

Regards
Bernd Edlinger.
