TCP/IP stack: robustness agains port scan


I was questioned about the eCos' stack robustness against the port scan.
I performed a very simple test with this configuration:
- stack: OpenBSD
- CPU: ARM7, 66MHz, 8kB cache
- stack buffer: 256kB (default)
- application running on eCos: tcp_echo.
All the other stack parameters set to default values.

I run from a linux machine nmap with the parameter "-p 1-" in order to scan all ports and this causes the crash of the eCos system.
Is it possible to improve the robustness against this port scan?

Thanks in advance.
