[Tim P]

Hi

Can anyone shed any light on this?

Compilation stops, all 8 cores are blazing away at 95% + and then it falls over.

My code has a lot of shapeless hlists in it.

Removing a couple of files and it is ok.

2.10.2 , sbt 13.

Since it is running out of memory, does it help if you add some more?
Like:
export SBT_OPTS="-Xmx1500M"

Cheers,
Juha

ok, yes, started experimenting - went with sbt -mem 2000 in the end. I didn't recognise it as a simple "you've run out of memory" at first.

sorry - anyone know how to feed this into intellij compilation process? I tried setting compiler process heap size to 2000 there but it doesn't fix it nor putting -Xmx2000M in the additional compiler vm options.
