Hello mayukmok00, thanks so much for taking the time to file this bug report and help make Ubuntu better!
The logs I see above don't help very much in determining what happened to your server. However these two lines are very telling: [Tue Oct 12 15:28:09 2010] [notice] Apache/2.2.14 (Ubuntu) DAV/2 SVN/1.6.6 mod_fcgid/2.3.4 PHP/5.3.2-1ubuntu4.5 with Suhosin-Patch mod_ruby/1.2.6 Ruby/1.8.7(2010-01-10) mod_ssl/2.2.14 OpenSSL/0.9.8k configured -- resuming normal operations [Tue Oct 12 15:28:56 2010] [error] server reached MaxClients setting, consider raising the MaxClients setting The sever reached MaxClients in under 60 seconds of uptime. Also I see PHP, fcgid, and Ruby all in this one server, so its possible other things are using up all of the RAM. In short, I believe this may be due to the web applications you are serving, not any bug in php. Can you repeat the sequence which causes the problems on a machine that is not serving heavy production traffic? Also something that would be useful would be the output of: ps auxww | grep www-data Which should show the running swelled up processes. Thanks!
