Hi everyone,
enif_send: env==NULL on non-SMP VM
is the error I'm getting when runing a CB application under CB 0.8.12 with erlang R17 in a Ubuntu 14.04 in a m3.medium AWS EC2 instance.
It seems erlang does not start with smp by default in my instance.
$ erl
Erlang R16B03-1 (erts-5.10.4) [source] [64-bit] [async-threads:10] [hipe] [kernel-poll:false]
$ erl -smp
Erlang R16B03-1 (erts-5.10.4) [source] [64-bit] [smp:1:1] [async-threads:10] [hipe] [kernel-poll:false]
What is the proper configuration to force -smp enable flag when starting a CB application?
Kind regards.

I think I solved it: found I can use vm_args, a property in the config file (boss.config) where you can add vm args such as "-smp".
Btw, vm_args is not documented in https://github.com/ChicagoBoss/ChicagoBoss/wiki/Configuration
Regards.

How did you add the vm_args entry for smp to the boss.config?
