[Tile-serving] [openstreetmap/mod_tile] Segmentation fault on a command "sudo -u taras renderd -f -c /usr/local/etc/renderd.conf" (#165)

[Taras Sara]

Good afternoon dear all.

I definitely need your help because I am new to Apache technologies and do not know how to some current problem.

Could you be so kind to inspect my code and assist me to find the solution. I will greatly appreciate that.

I am following stages written in a manual: [switch2osm_16-04-2-lts](https://switch2osm.org/manually-building-a-tile-server-16-04-2-lts/)

But on a stage of "Running renderd for the first time" I got problems.
When I execute next command `sudo -u taras renderd -f -c /usr/local/etc/renderd.conf`
I received next reply in my Terminal:
```

What does it mean Segmentation fault and what should I do?

Also, when I open my browser [http://130.89.234.165/mod_tile/0/0/0.png](http://130.89.234.165/mod_tile/0/0/0.png) I got next reply on the black background:
`The image “http://130.89.234.165/mod_tile/0/0/0.png” cannot be displayed, because it contains errors.`
Thank you fellows.
