It could be many things. From congestion of the network to bad programming. If you are
sure the problem is with the net, discover if it's half or full-duplex. If it's
half-duplex, go to your hub or switch and discover if there are too many collisions
going on (there should be a yellow or orange light flashing everytime a collision
happens).

Try using a sniffer or a traffic analyzer to find out how much bandwidth is being used.

If there's enough bandwidth left, there are no collisions going on, it could be a
computer set up problem (MTU etc).

No. If the line is cut during a transmission, the receiver won't be able to check 
things
like checksums with an incomplete packet. So, it will drop it.

(I'm not sure if it won�t send out an icmp message with parameter problem. But I think
not.)
