ERROR: for bob-lnd  Cannot start service bob-lnd: driver failed programming external connectivity on endpoint bob-lnd.sphinx (f3203a19e10b8f065727923e0a9fcec427180a8d857a4005517a31f81f609b79): Error starting userland proxy: listen tcp4 0.0.0.0:38882: bind: address already in use

sometimes at random an integration test in sphinx-relay fails early because a port is already in use
this is always the same port (38882) and it's always bob-lnd
EDIT: just saw this also for dave... there must be something with this port range

can this port be changed to something different?

relevant code:

$ grep -rn 38882
lnd/setup/nodes/proxynodes.js:55:    hostname: "bob-lnd.sphinx:38882",
lnd/setup/nodes/nodes.js:50:    hostname: "bob-lnd.sphinx:38882",

i ran lsof -i -P -n in an integration test workflow (3rd item) and yes, ports in this range are in use
