Re: [ns] TCP and packet drop: where are the retransmitted packets?

Takuya, Well it sounds very much like a floating point exception is being thrown somewhere in your code. Try finding where and fixing the code. hint gdb is a pretty good debugger with some fairly good GUI's available for it if you're that way inclined! /hint Matt On Tuesday 27 June 2006
