ASR multicast... Could not write data: No buffer space available

[coiner]

I am trying to multicast a disk image to multiple iMacs (newest 21.5" model) using ASR. Here is my plist config for the server:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Data Rate</key>
<integer>12000000</integer>
<key>Multicast Address</key>
<string>224.77.2.121</string>
</dict>
</plist>



I use the following command to start the server:

sudo asr -source labmac.dmg -server multicast.plist

The terminal responds "Ready to start accepting clients"

Then I go to one of the iMacs that will receive the image. I am netbooting the client off of the same server that is multicasting the image over ASR. I try to start the imaging process by issuing the following command on the client:

sudo asr -source asr://server.ip.add.ress -target /Volumes/Macintosh HD -erase

The command is accepted, confirms that I would like to erase the drive, and then says "Restoring" but no progress shows.

Back on the server, the terminal will output the following continuously until I cancel the multicast:

Starting stream Sun Feb 10 15:55:10 2013
asr: Could not write data: No buffer space available






The multicast seems to be working because the entire network gets bogged down, so why is it that it is unable to transfer the image data?
