[ns] Segmentation fault at the end of simulation

[Michael Sidiropoulos]

Hi Manjusha,
  and happy new year to all ns-2 users!!
  
  some thoughts that might help you:
  1)visit this link:
  
  
http://inesc-0.tagus.ist.utl.pt/~pmsrve/ns2/ns2_debugging.html#_Toc122255042
  
  it is a ns-2 debugging page to find out what your problem is.
  
  2) try putting in your tcl script instead of
  
  
set val(ifq)        Queue/DropTail/PriQueue

the line:

set val(ifq)         CMUPriQueue

if that don't help the problem might be ( i am  not sure )  that   
you are  running out  of  memory.Read  his page :
  
   http://www.isi.edu/nsnam/ns/ns-largesim.html
  
if you follow the instructions there i think that you will manage to 
save some memory.
  
  Bye!!
  Michael

Hello NS-users,

I'm getting a strange error while running wireless simulations using 
DSR 
protocol. After a simulation run of 200sec with 120 nodes, the system 
is receiving a 
SIGSEGV, segmentation fault in Tcl_FindHashEntry(). The packets are all 
getting 
delivered to the destination & packets in transit are getting dropped 
at the end of 200sec, 
as usual. But, I'm unable to trace the cause of the seg fault. Has 
anyone got a 
solution to this problem? Do reply at the earliest.

Regards,
Manjusha
