To properly diagnose the problem, we need a backtrace to see what is happening behind the scenes. To find out how to generate a backtrace, please read http://bugs.php.net/bugs-generating-backtrace.php for *NIX and http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32 Once you have generated a backtrace, please submit it to this bug report and change the status back to "Open". Thank you for helping us make PHP better. Specifically, we're going to need a backtrace with debug information, I think. ------------------------------------------------------------------------ [2012-12-17 06:14:02] lys0212 at qq dot com Description: ------------ Recently, the new a server used to make web, configuration, software installation, etc. And now the production environment is the same.
