feature-classifier stopped with "Killed"

[jko]

Hello everyone,
I have a problem.
I used tutorial by SoilRotifer to processing, filtering and evaluation the SILVA database with Rescript from this forum: https://forum.qiime2.org/t/processing-filtering-and-evaluating-the-silva-database-and-other-reference-sequence-data-with-rescript/15494

I got SILVA data by Hard Mode, filtered sequences by length and taxonomy and I stopped on:

*qiime feature-classifier fit-classifier-naive-bayes *

• --i-reference-reads silva-138.1-ssu-nr99-seqs-derep-uniq.qza *
• --i-reference-taxonomy silva-138.1-ssu-nr99-tax-derep-uniq.qza *
• --o-classifier silva-138.1-ssu-nr99-classifier.qza*

Unfortunatelly the function stops running with the output "Killed".

I tried looking for solutions on this forum and I found information (from 2017) that it may be out-of-memory error. I’m using Linux on Virtual Box, folder which I working on has 6,9 GB and free space is 169,4 GB.
Maybe someone has an experience in this problem?

Thank you in advance for your help!

Best regars,

Hello and welcome to the forum!

Looks like you are running out of the memory (RAM).
Try to request more RAM (if you are using HPC), increase available RAM for VM (if there is a room for it) or switch to more powerful machine.

Best,
