--- Comment #1 from Mike Walker <mwalker@carbonhouse.com> ---
Also I can replicate this with TCP as well as UDP.


Example TCP transfer test-case commands, right now this reliably stalls around
12-15MB into the transfer, going at 1.36MiB/s:

################
# client:
dd if=/dev/urandom of=rand100M.bin bs=1M count=100
pv -pterbT rand100M.bin | nc -v  34.242.134.36 31337

# server:
nc  -v -k -l 31337 | pv -W -s 100000000 -p -t -e -r -b -T > /tmp/rand100M.bin
################

Example UDP transfer test-case commands, right now this reliably stalls around
2-3MB into the transfer: 

################
# client:
dd if=/dev/urandom of=rand100M.bin bs=1M count=100
pv -pterbT rand100M.bin | nc -v -u 34.242.134.36 31337

# server:
nc -u -v -k -l 31337 | pv -W -s 100000000 -p -t -e -r -b -T > /tmp/rand100M.bin
