problem playing streams created on server

[gaby]

hi, i made a visioconference room using wowza server.
i have a weird issue, and at wowza they told me it's a bandwidth issue, but i hardly believe it when i take a look at the figure...here is the deal:

i have on user, who is the source, broadcsting audio/video to the room (about 15kbps)
on another computer in the same room, i am playing the main stream, so it is 15kbps download.
now i have several movies in which i am calling the following code:

var confStream:NetStream = new NetStream(_root.client_nc);
my_video.attachVideo(confStream);
confStream.play(_root.usersList.selectedItem.ID);
confStream.onStatus = function(infoObject:Object)
{
trace("onStatus: "+infoObject.code);
}

so when launching this script with a button,i can see in the server logs that there is a call for a stream creation, and the stream is created...but the play command is issued later, sometimes few seconds, sometimes 1 minute, sometimes never...i precise that streams are not overided in the client movie, as the script is called in separate movies...so only the netconection is relative to root, streams creation are handled in separate movies...

wowza is running on dual core red hat server, 1gbps bw, 4Go ram, and there is only wowza on it...

i usually have over 100 persons in the same room and its working perfectly...but for this specific function, it almost never work...

does someone have an idea of what it could be...do you think this can be a bw issue..?
thx for your help

Are you sure that NetConnection is connected successfully prior to create and attach the NetStream?
