To benefit others who are using meteor 1.6.1.1 and are seeing core dumps in production
and to give clarity to earlier advice I have seen floating about …
do NOT use node v8.11.1 as it tends to core dump many times a day
Also avoid using node v8.9.4 even though that was the suggested solution - it also core dumps on 1.6.1.1
Instead use node v8.11.2 when using meteor 1.6.1.1 which runs fine and is core dump free - hooray !!!
In my shop we have rolled our own production deployment tooling so are not using Galaxy which evidently is or was using a patched node v8.11.1 … When my system cuts a new domain deployment it gets its node executable by doing a wget from https://nodejs.org/download/release/
Enjoy !
