Massive Write IO 391GB - no exit, so very very slow.

[mohclips]

I have only a few subdomains, but i am finding this app does not exit after 6+hours.

Can you please suggest some tweaks - so that it runs to completion?

docker run --rm -it -v /home/bbp/shuffledns/tmp:/tmp -v /home/bbp/shuffledns/output:/app/output -v /home/bbp/shuffledns/../n0kovo_subdomains/n0kovo_subdomains_small.txt:/app/wordlist.txt -v /home/bbp/shuffledns/../resolvers/resolvers.txt:/app/resolvers.txt shuffledns:latest -v -mode bruteforce -duc -w /app/wordlist.txt -d staging.dice.fm -r /app/resolvers.txt -o /app/output/brute_subdomains.txt

The DB and log files do not look all that large for the amount of IO.
