Hello Alan,
Thanks for your reply.
I know that icmp is being handled by the router's cpu and that the
forwarding is being done in hardware.
The interesting part here is that the loss starts at the router where the
asynchronous routing begins and is even being seen at the final destination
host - but this only happens with pathping and mtr. An ordinary ping doesn't
show this problem.
The problems in mtr/pathping disappear when a synchronous routing is being
established.
What's the case for this? What are the programmers of mtr and pathping doing
wrong or is there another problem mayb in the implementation of icmp?

there is no real loss.
