Hi there @MarcoT!

This usually indicates that DADA2 ran out of memory while processing.

It looks like you might be using the VirtualBox image (based on the filepaths in your traceback; can you please confirm though). You should might be able to increase to allocated memory to the virtual machine, assuming your host machine has more to spare. There are several posts floating around on the forum that describe how to increase the memory of a virtual box machine.

Let us know how that goes! 🦖 :qiime2:
