@vheidrich,

Can you provide more details about your SILVA database? How did you make it? Are you using the pre-made sequence and taxonomy files provided on the [Data resources page](https://docs.qiime2.org/2021.4/data-resources/#silva-16s-18s-rrna)? or making it yourself using [RESCRIPt](https://github.com/bokulich-lab/RESCRIPt)?

Given that the raw SILVA db is large, we'd recommend at least dereplicating the silva data as outlined in the [RESCRIPt tutorial](https://forum.qiime2.org/t/processing-filtering-and-evaluating-the-silva-database-and-other-reference-sequence-data-with-rescript/15494), to avoid memory issues similar to what you are observing.
