Silva files don't work in dada2 Docker container

[abremges]

Silva files result in cryptic error message if executed within Docker...
Executing dada2 with Silva files outside of the container works just fine.
RDP files work fine, no matter what, inside and outside of the container.

My fault: I did not grant my local Docker enough memory to load the (bigger) Silva files. Similar error with centrifuge, where loading the index resulted in the same cryptic error message. No bug, closing.
