Hi, I am running qiime2-2019.7. when I ran my dada2, the following error message came: "An error was encountered while running DADA2 in R (return code 1), please inspect stdout and stderr to learn more."
I started to research around the problem, so I ran the same on another server, and seemingly my files were OK (e.g. equal number of R1 and R2, etc).
Then I came back to my server and saw that I can run the thing on 1 thread, and on 2 and 12, but it dies on 24 thread and up.
Here below is the successfull command and timestamp and success message and the 24-thread command and error message, and I am attaching the error log files.
