Bug #64924 [NEW]: 500 internal server error caused by PHP but nothing logged in error log

From: matteosistisette at gmail dot com Operating system: ubuntu 12.10 PHP version: 5.4.15 Package: *Web Server problem Bug Type: Bug Bug description:500 internal server error caused by PHP but nothing logged in error log Description: ------------ I have no idea what's triggering this, certainly some error of mine in my php code, however, in very rare cases I'm getting 500 internal server errors which are logged as such in apache's access_log, but don't log ABSOLUTELY ANYTHING in PHP's error log, not even a fatal error or parse error. I only get an empty 500 response from the server. Such a thing must never, ever, ever happen, no matter what, if the error is caused by php code. -- Edit bug report at https://bugs.php.net/bug.php?id=64924&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=64924&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=64924&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=64924&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=64924&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=64924&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=64924&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=64924&r=needscript Try newer version: https://bugs.php.net/fix.php?id=64924&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=64924&r=support Expected behavior: https://bugs.php.net/fix.php?id=64924&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=64924&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=64924&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=64924&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=64924&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=64924&r=dst IIS Stability: https://bugs.php.net/fix.php?id=64924&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=64924&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=64924&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=64924&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=64924&r=mysqlcfg
