[ns] Packet copy: error

[sbegum <sbegum@usc.edu>]

Hi,

I am getting scheduler error "Event UID not valid"
during my simulation of wireless adhoc protocols.
It seems that it happens occasionally right
after a module uses copy of a packet rathen
than a packet itself for sending. Now, have put
a check in some of those modules and seen
that after packet copy (for example,
channel::sendUp module), uid_ of the
copied packet is not same as the
original packet. This might be the problem
causing scheduler error.

Can anybody help me out? Specifically,
I wanted to know the reason for not
having the same uid_ in the copied packet.
Is it because of a memory problem? Has
anybody faced this problem and if so,
how to get around.

Any help is appreciated..

Thanks,
