As others have pointed out, you probably have a switch with small buffers.

If you also have flow control and you have something that triggers flow 
control to turn off packet forwarding, your small-buffer-switch might fill 
up all (shared) buffers on that port and now you're dropping traffic to 
all ports.

So trying to find if you have something where flow control is enabled and 
is being triggered might be something worthwhile to do, and also perhaps 
just turn off flow control on all ports to make sure.
