Hey,

A couple quick checks; make sure the server executable is actually, well, the server executable.
Someone could've replaced it with a skiddy tool.

If that doesn't show any joy, run

netstat -n

Theoretically, anything pushing out that much bandwidth will be hammering the I/O a bit, so iotop should show you the offending process(es)
Post the results if you're unsure about what it means
