I think I know what this was…at least my Galaxy server is now no longer crashing.
I use many 3rd party packages (wherever possible, frankly, though I try to stick to well used ones) and I guess the more you use the more you expose yourself to incompatibilities with core upgrades. I believe my problem was due to this package:
I can’t be 100% sure and my sincere apologies to the author if this is not the case. But it seems very likely. Though it’s not really the package’s fault probably as it merely wraps this NPM package:
Trouble is I think it’s wrapping a really old version that is the likely culprit for crashing my Meteor V1.6 server. I guess using packages that merely wrap NPM packages is a bad idea now that you can use NPM proper. That said, I couldn’t get the latest NPM version to work either so I’ve ended up using another package that wraps a later version:
Which works! Though I guess I’m storing up a problem for later when some upgrade will break this one too!
Summary: Beware legacy packages and anyone out there who is using quackware:ical-generator - be warned when you upgrade to Meteor 1.6.
