Bug #67889 [NEW]: funny Fatal error during apache shutdown

From: php at bof dot de Operating system: openSUSE 11.4 PHP version: 5.5.16 Package: opcache Bug Type: Bug Bug description:funny Fatal error during apache shutdown Description: ------------ Recently upgraded production webserver to PHP 5.5.16 with opcache (previously 5.4.26 with APC), I notice that when I shut down apache (while there are still some connections in flight / in processing) the following messages in php error log. The call to microtime() that is mentioned there happens at request shutdown from within a class instance __destruct() method of an object that is the sole singleton instance of its class (static protected $instance). How can microtime() be gone at that point in time??? In normal operation everything is fine with this mechanism, it is only when shutting down apache that this happens - which makes me suspect opcache (but not sure) Unfortunately I could not reproduce this on a nonloaded development system so far... Here's the fatal error log entry: [23-Aug-2014 01:19:39 Australia/Queensland] PHP Fatal error: Call to undefined function microtime() in /.../classes/counter/loadtime.inc on line 184 [23-Aug-2014 01:19:39 Australia/Queensland] PHP Fatal error: Cannot call overloaded function for non-object in Unknown on line 0 Destructor code: public function __destruct() { static::stop(); } That method's code starts like this, up to the line 184 microtime call of the log: static public function stop() { $that = static::$instance; if (!isset($that) || !isset($that->page)) { return; } $now = microtime(TRUE); and the second message about call overloaded function on non-object, probably comes some lines later as "$that->get_cpu_usage();" (there are no other objects involved up to that point) PHP 5.5.16 is running as mod_php under the openSUSE 11.4 (evergreen) apache 2.2.17 server (up to date).
