While making some tests on an Apache 2.4.3, I found something which looks like a bug to me (but maybe I'm wrong?).

The default value for "LimitRequestBody" directive is zero, which means "no limit". But, when you send a "big" request, you receive a 413 error code.

This comes from the file "mod_proxy_http.c", line 590, and a fix could be:
--- a/src/modules/proxy/mod_proxy_http.c
+++ b/src/modules/proxy/mod_proxy_http.c
