Description:

Hi,

I ran a same tcl file in both ns-2.27 and ns2.19b. ns-2.27 reported "Segmentation faut" error. But ns-2.19b did not report any error(It worked well).
In this tcl file, I set the packet interval as 0.008s. While I adjusted the packet interval larger(such as 0.08s), no error happened in ns-2.27.
What's the problem? Please teach me.
Thank you very much!
