lnd sometimes fails to listen #29

Closed nayuta-gondo closed 5 years ago

nayuta-gondo commented 6 years ago

lnd sometimes fails to listen.

System: Ubuntu 16.04.4 LTS x86_64

Sometimes lnd fails to listen when running tests in succession as follows("address already in use" error).

py.test -v test.py -s

It does not happen if each test is run alone as follows.

py.test -v test.py -s -k 'test_gossip[lnd_lnd]'

My guess is that the specified port is TIME_WAIT state after the previous test run.

test.py::test_gossip[lnd_lnd] listen tcp 127.0.0.1:36332: bind: address already in use

Good catch, I observed something similar and was expecting it to be related to an unclean shutdown of lnd hence I made the shutdown a bit more forceful.
