Stuck with no progress on Update

[d3mon187]

I'm trying to get a planet import to do an osmosis update, but it appears to freeze after processing nodes, ways, and relations. Looking at the database, the only active query is - COPY "place" FROM STDIN. According to my server stats I can see that the query is using tons of disk IO at 200-400MB a second. Still, I have let it run for over 2 days, and the osmosis import showed no updates on progress. I tried using the latest osm2pgsql version from master, as well as updating Nominatim from 3.5.1 to 3.5.2. Am I missing something? Thanks!

sudo docker exec -it nominatim sudo -u postgres ./src/build/utils/update.php --verbose --import-osmosis --osm2pgsql-cache 22000

The check_import_finished.php script at the end of init seemed to indicate that everything was ok, but after running it again it stated that indexes were missing. After running "--index --create-search-indices --create-country-names --index-noanalyse" two more times, the check_import_finished.php script finally said that all indices were good.
