[ns] Problem with wireless simulations !!

[Valerie Alandzi]

    Hi,

I have not yet debugged my code for error "Scheduler:
Event UID not valid!" because now I've got another bug
...

At ~60s, the simulation apparently stops, I mean Ns
keeps on running (it does not stop) but nothings more
is written on the trace file. I don't get any error
message, even with DDD. So I really don't know what
the problem is ...

Please, can someone help me with that ?

Regards,
