RE: Site performance, Server errors, outages and tunings - Like Ra - 14 Dec 2011 Nice... One of the reasons I prefer CLI over GUI. Last night I added a AAAA DNS entry. And no, I did not forget the trailing dot for the name. But the GUI ignore the dot. Ha-ha ... Also it turned out, that the DNS manager does not accept @ as the domain name (but it uses @ in the zone file), but expects empty name to refer to the domain. It costed me hours of downtime and cache poisoning. Crap.... Why does not it just work? 😁 RE: Site performance, Server errors, outages and tunings - Like Ra - 14 Dec 2011 The new zone is still not propagated everywhere. E.g. Google, gtmetrix cannot yet connect. RE: Site performance, Server errors, outages and tunings - Like Ra - 15 Dec 2011 The forum has been upgraded to the latest version. One plugin is incompatible (View unread post). Upgrading plugins... RE: Site performance, Server errors, outages and tunings - Like Ra - 15 Dec 2011 Lots were changed in 1.6.5. Let me know if something is broken. Removed the AAAA record from the DNS. I wonder if the glitches with resolving are related to IPv6. RE: Site performance, Server errors, outages and tunings - Like Ra - 15 Dec 2011 It was, indeed, the AAAA DNS record. After I removed it Android can see the site again. RE: Site performance, Server errors, outages and tunings - Like Ra - 15 Dec 2011 The site design is broken in the latest Firefox Beta Mobile, no problem in the native Android browser. RE: Site performance, Server errors, outages and tunings - Like Ra - 17 Dec 2011 Dunno what happened. Just like earlier: at 14:00 GMT all the memory was used and swapping killed the VPS. Rebooting helped. How do I limit the amount or running apache processes? Both HTTP daemons and PHP? Apparently whatever I do does not work. RE: Site performance, Server errors, outages and tunings - krinlyc - 18 Dec 2011 Hmm, how did you configure your apache2 and php? You should use the mpm-woker module and with that fast-cgi (fcgi). Use google to find some infos on that. This http://www.marco-rust.de/worker-vs-prefork-mit-php/50/ is a cool site describing how to tune that combo. It is in German, but if you have some trouble with understanding ask me - I ll help you bye krinlyc RE: Site performance, Server errors, outages and tunings - Like Ra - 18 Dec 2011 (18 Dec 2011, 10:09 )krinlyc Wrote: You should use the mpm-woker module and with that fast-cgi (fcgi).Not using fast-cgi. But you are right about mpm. This is exactly what was wrongly configured. Bobbi (https://the.tiesthatbind.me/ ) and I figured that out yesterday. all settings were inside the MPM tags, but no MPM module was installed. So, I moved them outside of the tags, decreased the MaxClients even more ( it's 50 now) and here's the result: [Sun Dec 18 13:25:58 2011] [error] server reached MaxClients setting, consider raising the MaxClients setting It works! And the OS was not out of memory as before.

Otherwise it is somehow as if you drive a Porsche in second gear.... And even more important is the fact that mpm is not threadsafe; mod_php is not aware of this fact. krinlyc |
