We will discuss whether/how to fix this on the dev@ mailing list, in the meantime I'd suggest that: > [Sun Oct 17 15:53:48.180621 2021] [http2:warn] [pid 3581] AH10034: The mpm module (prefork.c) is not supported by mod_http2. The mpm determines how things are processed in your server. HTTP/2 has more demands in this regard and the currently selected mpm will just not do. This is an advisory warning. Your server will continue to work, but the HTTP/2 protocol will be inactive. .. you do not "LoadModule http2_module mod_http2.so" in your MPM prefork configuration, because due to its multithreaded nature (unlike MPM prefork) mod_http2 implies that mod_proxy will have to allocate/handle multiple simultaneous connection to the backend which is what is causing the crash here. > [Sun Oct 17 15:53:48.181146 2021] [lbmethod_heartbeat:notice] [pid 3581] AH02282: No slotmem from mod_heartmonitor Likewise you probably don't need lbmethod_heartbeat and several modules in your list, so I'd suggest that you cleanup your LoadModules a bit, ideally to the strict minimum needed.
