[-- Attachment #1 --]
I am having difficulty sending out Mbone media streams. Every receiving station is 
experiencing packet loss (>40%). We have determined that this could be a result of 
insufficient memory in the send and receive buffers. I have attempted to modify these 
settings with the "sysctl" command. The commands and parameters used are as follows: 

        sysctl -w kern.maxsockbuf=1048576 
        sysctl -w net.inet.tcp.sendspace=1048576 
        sysctl -w net.inet.tcp.recvspace=1048576 
        sysctl -w net.inet.udp.recvspace=1048576 

After making these modifications I experience errors when I try to launch the Session 
Directory or X Windows. The errors are as follows: 
 
    SDR Error 
    couldn't get SIP receive socket: no buffer space available 

    XWindows Error 
    _XSERVTransSocketOpen: socket() failed for tcp 
    _XSERVTransSocketCOTSServer: Unable to open socket for tcp 
    _XSERVTransMakeAllCOTSServerListeners: failed to open listener for tcp 

Any suggetstions? 

Thank You,
