(I am not sure how long you had between cycles of your while loop, but I
as far as I can tell it's normal operation for the spawned "noop"
process to remain defunct for a short period of time while the main
amandad process copies the noop process's data back over the network to
the server, but then once that copying has finished the "noop" process
is cleaned up.
Probably the same thing would happen with the "sendsize" process -- but
since that is never finishing you never get to the point that there's a
defunct sendsize process.
Then defunct "amandad" processes, on the other hand, seem to be
subproceses amandad spawns of itself to offload some work -- and as far
as I can tell those may not get cleaned up until amandad as a whole
exits.)
