Thanks for tracking this problem @RafaelAPB I added some more labels. It seems like one of those issues that I would know how to fix quickly because I've seen similar crashes from docker before, so, if you struggle to debug what the problem is just let me know and I can take a stab at it myself.

Thanks a lot, Peter. I'm not resolving this in the near future.
