had to reboot one of my servers and notice this in the log
[http2:warn] [pid 2139] 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.
couldnt find a lot about it on google but it has some thing to do with mpm_prefork being old and doesnt work with http2
so it there a mpm_prefork alternative i can try ??
