Hi guys!

I'm facing a technical issue and I have absolutely no idea what the problem could be. I tried to run the following command:

```
qiime feature-classifier classify-sklearn \
  --i-classifier SILVA/silva-132-99-nb-classifier.qza \
  --i-reads rep-seqs.qza \
  --o-classification taxonomy.qza
  --verbose 

```

The classifier artifact in use was downloaded from the following [source](https://www.dropbox.com/s/5tckx2vhrmf3flp/silva-132-99-nb-classifier.qza?dl=0). The other artifacts were created with help of the different tutorials.

After around 2.5h computing time my computer will restart and generate the following error message which I cannot decipher (see attached text file). I don't know if this is a hardware problem or if it could be a bug in the plugin.

Thanks for your help!

Yikes! Almost certainly sounds like a hardware issue. This does not indicate a bug with the plugin, but please let us know if you get any error messages from QIIME 2.

See [this apple forum discussion](https://discussions.apple.com/thread/4926603) to troubleshoot.

Good luck!

Thanks for your reply! I tried to run the command on another laptop and it worked.
