I'm in the process of optimizing our web application for performance and one thing that I was really excited to try was mod_http2 because it allows the browser to send multiple requests through the same TCP connection with compressed headers. However, when I enabled it and restarted apache I was greeted with this:
[Fri Jan 25 12:30:57.813355 2019] [http2:warn] [pid 10186] 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. [Fri Jan 25 12:30:57.828217 2019] [mpm_prefork:notice] [pid 10186] AH00163: Apache/2.4.29 (Ubuntu) OpenSSL/1.1.0g mod_apreq2-20090110/2.8.0 mod_perl/2.0.10 Perl/v5.26.1 configured -- resuming normal operations [Fri Jan 25 12:30:57.828238 2019] [core:notice] [pid 10186] AH00094: Command line: '/usr/sbin/apache2' The last time I tried to use either mpm_worker or mpm_event my application was plagued by seemingly random segfaults. Are there any plans to support other MPM's? If not, the benefits of HTTP2 appear to be permanently out of reach for our mod_perl applications and that, honestly, might force us into seriously reevaluating our technology stack. :( -- John Dunlap *CTO | Lariat * *Direct:* *j...@lariat.co <j...@lariat.co>* *Customer Service:* 877.268.6667 supp...@lariat.co
