[Errno 12] Cannot allocate memory (Plugin error from feature-classifier)

Hi @SongkranTh,
Welcome to the forum!
The error you are receiving is due to insufficient memory available. The Silva database is huge and can easily eat up more than 22 Gig of RAM. Your options are to a) allocate more memory, b) use the GreenGenes database which uses considerably less memory, or c) try some parameter adjustments as outlined here. Hope that helps!
