[ns] NS 2.1b7 locking up

[Jay Jeon <wjjeon@ece.gatech.edu>]

Hi,
 
I'm wondering if any of you could try running the "master.tcl" file I've
attached to this e-mail. For some reason, the simulation "locks up" at a
certain point, meaning there are no error messages, yet it doesn't finish,
and if you look at the "master.tr" trace file the size has stopped
increasing. In my case the size stops at 1273856 bytes. This size is
different for other machines. However, it seems that for a given
machine, the size at which the simulator stops always stays the same.

I've tried checking the FAQ's and other online ns resources but haven't
been able to find anything about this. I've also tried applying the ns
2.1b7 snap shot on the website but it didn't seem to make any difference.

It's a really simple wireless TCP simulation. The master_mobility file was
created using:
"setdest -n 26 -p 0 -s 30 -t 1800 -x 1000 -y 1000"

I've also included "env.txt" which is part of the output from "setenv" so
that you'll have some info on the system I'm using.
 
I don't think it's running out of memory because similar simulations that
create trace files that are a lot bigger run fine. Could it be a bug with
ns?
 
Hope I've included all the required info, and hope to hear from you soon.

Thanks,
Jay.
