Yea, but.......yea, but......
It's obvious that pings will get slower when other traffic is on the link, ie, the ftp job, and that doesn't tell us anything.
If the ftp is running from node A to node B then I'd set up ping scripts in both directions. The question is what happens to ping response times when the ftp job 'hangs'? Do the pings stop completely (lost packets), or return to full speed (ftp is producing no traffic so ping is fast)?
At that time what speed are pings from node C to node A? And node C to node B? Does this show that the network interface on A or B has completely screwed up and not communicating at all? Or do both interfaces still work but ftp is hung?
Unfortunately, I think you need to run this test to destruction (until the ftp is completely stuffed and 'hung') and then see if you can get either or both interfaces to talk. If one node won't communicate then that's the node to investigate.
