Error while building the database 'std::bad_alloc'

[MinLuke]

Hello everyone, I have download microbial, archaea, parasitic worm and fungi genomes and then, to build the DB, I used the folllowing command

./krakenuniq-build --db ../reference/ --kmer-len 31 --threads 3 --taxids-for-genomes --taxids-for-sequences --jellyfish-hash-size 40000000

But I get this error message

Kraken build set to minimize disk writes.
Found 6 sequence files (*.{fna,fa,ffn,fasta,fsa}) in the library directory.
Skipping step 1, k-mer set already exists.
Skipping step 2, no database reduction requested.
Sorting k-mer set (step 3 of 6)...

And only database.idx and database.jbd are produced at the moment as files in my directory. How can I resolve this issue? thanks a lot
