tiny_mce.js Script kills Webpage on high traffic

[Stefan M.]

My WordPRess Page has a Varnish Cache server, that it can deliver 1'000'000 PageRequests within 1 hour.

WordPress Page is running find and HTML code will be delivered in ms. But the page is not showing up, as JS Script will be rendered.

When I remove this 2 lines from Frontend:

<script type='text/javascript' src='./wp-includes/js/tinymce/tiny_mce.js'></script>
<script type='text/javascript' src='./wp-includes/js/tinymce/langs/wp-langs-de.js'></script>

Then the page is showing up.

I blanked this 2 files on prod page, Frontend is working fine...
When I restore the original files, the page will be in endless rendering phase and never show up.

This problem occures only on "high" traffic days. On lower traffic days, everything is working fine.

Latest WordPress is installed. If you want to have a look on the installation at such a day, please get in contact with me.

TinyMCE is only loaded on front-end if it's required by one of the installed plugins or the current theme, not by default. This sounds like an issue with the particular environment.
