HUMAnN - RuntimeError: can't allocate lock

Microbial community profiling HUMAnN

Hello,

HUMAnN v3.6

I was running HUMAnN on some samples and noticed that it threw error msgs as below:

g__Streptococcus.s__Streptococcus_cristatus: 4215 hits
g__Streptococcus.s__Streptococcus_constellatus: 1974 hits
g__Lactobacillus.s__Lactobacillus_zeae: 35 hits

Total gene families from nucleotide alignment: 132161

Unaligned reads after nucleotide alignment: 43.7616719737 %


Running diamond ........

RuntimeError: can't allocate lock

I have run humann_test and it went well. The sample has about 130 million reads.

Here is my HUMAnN command

humann --input my_sample_fastq \
        --threads 12 \
        --memory-use maximum \
        -o sample_name_humann_out \
        --metaphlan-options "--bowtie2db <local_bowtie2_db_path> --offline"

I’m just not sure how to address the error. Could you please help me with the error?

Thanks!
