I am new to using apache and I ran into a issue and anyone who can help point me in the right direction would be greatly appreciated.

I am running apache 2.4.6 on centos7.

Here is a log snippet,
GET /css/vids/mov-data.mp4 HTTP/1.1" 404 219
GET /css/vids/mov-data.mp4 HTTP/1.1" 206 45403324

The some of the video and images are not loading. There is a video and it will load a few frames then freeze, there is another video on another page and it loads and plays fine. There is also a page where a few images will load but others will not.
Could it be a size issue, or a header range, or keep alive issue.
Thanks for any help.

GET /css/vids/mov-data.mp4 HTTP/1.1" 404 219
404 is file not found

/css/vids/mov-data.mp4 HTTP/1.1" 206 45403324
206 is partial which is most often due to the range header.

Here's the rub, Apache used to have EnableSendfile on by default (1.3/2.x/2.2) but it was changed for 2.4. Every request it serves is now buffered in memory before being sent over the wire. This can affect large files being served.

I deal with large files by having them served with EnableSendfile turned On but only for those. In a global area of my config I have
Code:
<Files ~ "\.(flv|iso|mp4)$">
  EnableSendfile On
</Files>


That works for me. You can also make Apache send it in one piece, not multiple, by also adding MaxRanges 1 to the above example

Code:
<Files ~ "\.(flv|iso|mp4)$">
  EnableSendfile On
  MaxRanges 1
</Files>

Thank you for the response,
I reloaded apache and i'm still getting the issue
I entered the code snippet into the httpd.conf file at the line numbers listed below. Did I enable it properly

113 <Files ~ "\.(flv|iso|mp4)$">
114 EnableSendfile On
115 MaxRanges 1 116 </Files>

350 EnableMMAP on
351 EnableSendfile on
352 MaxRanges 1

As well I ran httpd -V, and I got Server compiled with....
dose this mean that send file is enabled.
-D APR_HAS_SENDFILE
-D APR_HAS_MMAP
If you want to take a look at it, here is the web site http://mattshig.com/index.html
