Re: [ns] Problem with queue size

[Huike LI <huike@ee.mu.oz.au>]

Briefly go through your code, what you did is creat a queue-monitor every
time the loop record executed, so, of course the initilization make the
queue size as 0. Therefore, take this line out of the record proc, you
will get it.

Good luck.
