Half of this goes to kombu. kombu could use redis or some other transport (see `#322 `_), so fixing `#322 `_ will help this issue too. mongodb database files contain a lot of NUL bytes. So one can easily use sparse files to save space on disk: :: # service mongodb stop # cd /var/lib/ # cp -a --sparse=always mongodb mongodb.new # mv mongodb mongodb.old # mv mongodb.new mongodb # service mongodb start # # TEST mongodb # rm -rf mongodb.old Maybe later versions of mongodb do this already internally. The above was needed on mongodb from debian/stable. Documenting the ""make sparse"" possibility will also help this issue. }}}",task,closed,minor,0.0.5,documentation,FIXED,,,
