FC2 - Strange Ethernet Behavior

[John Krische]

Hello again.

As promised, here's some cleaned-up output from tethereal during a test 
download from the web.  I've obsured the local IP in question and have 
deleted entries that were unrelated local traffic.

Packet sequence ID's 97-179 ought to jump out at somebody.  That is 
definitely the moment of connection speed loss.  Of course, I have no 
idea what to do about it, which is why I'm here in the first place.  :)

Further info: similar behavior from a large mysql transaction to the 
server being tested above, inside the LAN.   However, no such behaviour 
on a large file (100MB) copy over Samba 3 from a win host to a share on 
the target machine.  That wored fine, blazing speed.  Most odd.
