I got the same issue. Sometimes it works, most of the time: segment fault.

[6112:0x103061600]      252 ms: [Finished reentrant Scavenger during Scavenge.]

Whene i use LTS version(v6.11.5) of node it works fine:
v6.9.0
v6.11.3
-> v6.11.5
v8.5.0
v8.6.0
v8.8.1
system
default -> v8.6.0
node -> stable (-> v8.8.1) (default)
stable -> 8.8 (-> v8.8.1) (default)
iojs -> N/A (default)
lts/* -> lts/boron (-> v6.11.5)
lts/argon -> v4.8.5 (-> N/A)
lts/boron -> v6.11.5

the results:
Nth Fibonacci # of workers latency in MS

@syahiaoui Thanks for the valuable feedback.
We just verified it works well by node <= v8.4.0 on linux, and it will fail with random callstacks by node >=v8.5.0
We are working to resolve this issue as our top priority, and we contacted node.js team to accelerate it. So, please try napa examples with node <= v8.4.0 before that.
Thank you very much.

This is tracked in nodejs/node#16658.

i have just upgraded to v9.6. i hope that library will support that soon

[fs-eire]

@jjhesk there was a bug to invalidate the workaround for this issue on Node 8.10.0 with Napa.js 0.2.0. Please update to 0.2.1 and have a try.
