When requesting a simple image file with HTTP2 every time MaxRequestsPerChild is reached, an empty response is sent to the client. This is even reproducible.
Server Version: Apache/2.4.41 (Ubuntu) OpenSSL/1.1.1f
Server MPM: event
OS: Ubuntu 20.04
Server Version: Apache/2.4.29 (Ubuntu) OpenSSL/1.1.1

Test command:
for i in {1..2000}; do if [[ $(curl -o /dev/null -s -k --http2 https://example.net/2101583.jpg?test=$i -w '%{size_download}') == 0 ]]; then break; fi; done
