I've seen that if I send echo requests very slowly, then invariably client times out. When I send icmp request from another client, it sorts of kick something in the stack, and the echo reply to the previous request packet also comes out. ??

Check your interrupts are working correctly. It sounds like you are
loosing interrupts, probably TX complete, so the next packet is not
getting sent until the next RX happens.
