wrapper.js crashes when /var/log runs out of space

My program crashed when launched from a /etc/init.d/ script created by node-linux

This is the error, from /var/log/parkberry-error.log:

```

```

Indeed, /var/log is full, and my program is to blame, but if node-linux is in charge of creating the log, it should be in charge or splitting/rotating it

```
pi@0000000023593fb2 /var/log $ df -h
