Apache error: command failed: failed to send file (file data)

Hi there,

As soon as I made a DNS switch and started sending actual traffic to my new droplet, I am seeing the error above in the apache2 error.log

The droplet hosts quite a simple website: http://www.buxenger.com

Website language: ASP.NET MVC 5 Web server: apache 2.4.7 + mod_mono Droplet: 4GB/2CPUs/60GB - Ubuntu 14.04 Region: Amsterdam

The error appears about 15 times per second (probably for every request) which often causes website to not be accessible:

Hello there,

Is the website built in a way that should load external content or send content from an external source? If yes then, this can explain the error in the log.

I also want to include great tutorials on Common Apache Errors and How To Troubleshoot Common Apache Errors that you can find really useful if you run into an Apache error and you need some help.

Also, this question was previously posted and answered by Bobby which you can check here:

Feel free to then share the output of the commands listed in that tutorial.

Hope that this helps!
