[ns] Floating exception

[Aco]

Hi all,

I have a tcl script that works for one tcp protocol and now added some lines 
for other tcp protocol. Script is working for first tcp protocol and when start 
simulation for new one I have simulation start and after some time (after few 
minutes) I have 

"Floating exception"

with no other output or details about error. At this moment the simulation 
stops, and enter another simulation (since I have many tests (simulations) 
started with one tcl script). Another simulation goes fine end and goes to 
third

Anybody can tell me how to trace where is this errorwhat files to look, how 
to log changes and how to find that  part of code .

I have read something where it is sead that this happens when I devide with 
zero (), or when I have variable defined as integer, and my script gives it a 
floating value  or something like that. But here, I don't know where to 
look , I have only this tiny output " Floating exception"

I am using ns2 ver.2.29. 


Thank you.
