Meteor server restarted^\Quit (core dumped)

What am I supposed to do when something like this happen?
Is there a log or something I can submit to MDG?

It happened after I added axw:json2csv package to my project (not immediately… so not sure it’s related to that)

Did it happen without the package being used, or while the package was being used? In other words, does that package have a memory leak?
