[MediaWiki-l] [SOLVED] RE: [Wikitech-l] Mediawiki - suddenly slow - suddenly fast - Apache error 408

Hello, Just a follow up. I think I've found the solution to the issue. Recap: VMware Workstation 10 running on Win7 SP1 x64 Web server: Ubuntu 12.04 Server x64, installed on a VMware machine, with 2 Go of RAM. Apache/2.2.22 (Ubuntu) MySQL 5.5.29 PHP Version 5.3.10-1ubuntu3.7 Mediawiki 1.21.1 or 3 APC 3.1.13 All work fine, but after a certain time (where the web server is completely idle), if I click on a link (of the wiki or not.. .it does the same for the index.html of the site), there's no response for over 15 to 20 seconds, and then the server respond properly. So the problem occurs only after an idle time and on the first request to the web server. Lots of errors in error.log (Apache): 192.168.75.1 - - [02/Oct/2013:16:05:50 -0400] "-" 408 0 "-" "-" Yesterday, for a(nother) problem on a real computer with the same configuration, I had to modify /etc/nsswitch.conf I had to replace the line: hosts : files dns by: hosts : files dns mdns4 Since then I never got the problem and tried several time to call the web server after an long idle time: all is ok. I don't know for now why it solves it (it's the first time I edit this nsswitch.conf file and have no knowledge on it), but it seems that if fixed the issue... if it can help someone.
