We need to reproduce this behaviour on our instance. Could you write more? I tried simple 'hello world' and it works:

$ cat hello.scm
(print "Hello, world!")
$ csi -s hello.scm
Hello, world!
$ csc hello.scm
$ ./hello
Hello, world!

I've also downloaded some benchmarks from:

https://github.com/ashinn/chibi-scheme/tree/master/benchmarks/gabriel

I've tested 'kanren.sch' using MooseFS 3.0.81, Ubuntu 16.04 and chicken scheme installed from packages (version 4.9 as I remember)

core@worker6:/mnt/mfstest/scheme/chibi-scheme/benchmarks/gabriel$ csc kanren.sch
core@worker6:/mnt/mfstest/scheme/chibi-scheme/benchmarks/gabriel$ ./kanren

It looks correct.

I've also checked it on Debian Jessie (64bit) and it also works fine.


Maybe we need something more sophisticated. Could you send us something that triggers this problem?

It doesn't matter. I use both 'oom_adj' and 'oom_score_adj', so it works fine. This is only disabling 'out of memory killer', so this is not related to any file operations.
