Folks,

I have now put a sniffer on my network to see what is happening when I get the
very long delay in loading the symbol table on my MVME162.  The sequence is
quite clear, but I am looking for clues as to what might be wrong.

ioc13idd is the MVME162 IOC, corvette is the boot host.

I have captured the end of the FTP load of vxWorks, which I think is happening 
up to packet 912 (?) This is a message from the IOC to corvette.  Note that
corvette takes almost 10 seconds to respond.  However, the really long delay 
(50 seconds) is between packets 930 and 931, which are both from corvette to 
the IOC. Did corvette expect a response from the IOC after packet 930 which 
it did not get, or what is causing this huge delay?  Any pointers will be most
appreciated.

                                    Thanks,
                                    Mark Rivers
