Compilation fails when run on a server with 122GB of RAM #154

Closed andreausu closed 7 years ago

Hello,

we're running into a weird issue on our CI pipeline when we use an AWS server with 122GB of RAM (i3.4xlarge):

./node_modules/.bin/elm-make --debug src/Main.elm 
[                                                  ] - 0 / 2Stack space overflow: current size 99136 bytes.
Use `+RTS -Ksize -RTS' to increase it.
elm-make: thread blocked indefinitely in an MVar operation

Using a i3.2xlarge instance instead that "only" has 61 GB of RAM works just fine.

The build is run inside a docker container so we are 100% sure that the software / environment is identical between the 2 nodes and the underlying OS as well since we're spinning those up using the same AMI and in a fully automated manner.

We've also tried limiting the available RAM via docker-compose configuration to no avail.

Do you have any idea of what's going on or how to debug this further?

Best, Andrea

Thanks for the issue! Make sure it satisfies this checklist. My human colleagues will appreciate it!

Here is what to expect next, and if anyone wants to comment, keep these things in mind.
