[ns] Segmentation fault at the end of simulation

[manjusha@cse.iitm.ernet.in]

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
