I only happens when I add a new Inputfield module (not happens with other types!) if the error wouldn't be strangely enough already added Inputfield module seem to work. I found some infos out there but all seem not to be related and it seems like a apache/php/hardware problem.

I am using FuelPHP framework. The web app is working fine. But suddenly today I created new controller, which itself is a copy of another controller. The one I copied from works fine (http://localhost/myapp/admin/users), but the copy (http://localhost/myapp/admin/apartments) makes me that error?! I am frustrated over this. After 3 hours of debugging I finally found the line where the whole things stops. It is in the FuelPHP core in Router class at this line if (class_exists($class)). The $class before the if has value Controller_Admin_Apartments, which is the class I have added and exists in my controller classes folder. fuel/core/classes/router.php: protected static function parse_segments($segments, $namespace = '', $module = false) { $temp_segments = $segments; foreach (array_reverse($segments, true) as $key => $segment) { $class = $namespace.'Controller_'.\Inflector::words_to_upper(implode('_', $temp_segments)); array_pop($temp_segments); if (class_exists($class)) // ***** HERE ERROR HAPPENS ***** // { return array( 'controller' => $class, 'action' => isset($segments[$key + 1]) ? $segments[$key +
Modified: 2007-03-21 15:23 UTC From: pbugs at ausschlafen dot com Assigned: Status: Closed Package: APC (PECL) PHP Version: Irrelevant OS: Linux 2.4.16-64GB-SMP Private report: No CVE-ID: View Add Comment Developer Edit [2007-03-19 13:17 UTC] pbugs at ausschlafen dot com Description: ------------ Hi, I tried to upgrade APC and php together. What I have is php 4.4.6 and APC 3.0.13, running under Apache 1.3.37. I took a sample of all unique GET URLs of my live site and replayed them on the test server, so the test is not run in a high load environment. Nevertheless, sooner or later during the replay, apache childs crash with : [notice] child pid 30366 exit signal Bus error (7) As long as the APC console is working, it does not show any problem; no fragmentation and the memory usage is not more than 50% of the 64 MB I assigned to APC. After the errors occur, the server is unstable. Static files can be served, but the APC console (and most - but not all- other php apps and scripts) don't work any more. The crashes do not always occur at the same step of the URL replay; in this respect I can not pinpoint a single script or application. However, multiple test runs repeatedly failed sooner or later. Apache has to be restarted then. Occasionally I see [apc-error] Cannot redeclare classes in the Apache error log when some wordpress blogs are accessed. The PHP error log remains empty (E_ALL), however. These happen to appear shortly before the "Bus errors", but I don't know whether there is a connection to the crash or not.
