Fix Fatal Error: Allowed Memory Size Exhausted in PHP

fatal errormemoryPHP

I've seen this error elsewhere, but the general consensus seems to be "Increase the allowed memory PHP has". Ours is already at 1GB, so I'd like to figure out (if possible) what's going wrong here.

The full error is:

Fatal error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 523800 bytes) in /lib/Zend/Locale/Data.php on line 819

Then, in the Data file mentioned, line 819 is the citytotimezone case:

case 'citytotimezone':
    $_temp = self::_getFile($locale, '/ldml/dates/timeZoneNames/zone', 'type');
    foreach($_temp as $key => $found) {
        $temp += self::_getFile($locale, '/ldml/dates/timeZoneNames/zone[@type=\'' . $key . '\']/exemplarCity', '', $key);
    }
    break;

This intermittent error just started happening within the last week or so, but we've not made any relevant changes that should be affecting this.

How can I begin to debug this issue?

We are using PHP 5.3.10, if that's relevant.

It's hard to say exactly why that chunk of code is trigging the memory error without more context - a stack trace, description of what actions are ongoing when the error occurs, etc.

But, I can definitely say that by going with a more modern version of PHP you will see decreased memory usage. You could always manually raise the 1GB, but even if you do that you will see more benefit with PHP 5.4 or 5.5. More information on PHP memory here.

What version of Magento are you using? Double check the system requirements here and be sure you meet them all.

It looks to me based on what you state at the start (run reindex all) that you are currently using the command line shell/index.php to do your reindexing.

In the default configuration of servers, PHP runs two ini files one which deals with command line, and one which deals with your web server. So the .htaccess information would not actually be used.

Depending on your server configuration, there are a few places that the file may exist so if you have a look in

/etc/php

/etc/php5

You will hopefully find a sub directory structure which reveals a cli folder perhaps under conf.d and within that you will have the php.ini file which is used to configure the CLI tool you are using. This file needs to have the value for memory_limit increased.

If you run a phpinfo() from the CLI you may find it will tell you in the output the actual ini file loaded (and of course the information to do with the current values.

Hope that helps.

You can add the following in index.php - make sure the log file path is correct

function shutdownCapture() {
    global $lastQueryString;
    $error = error_get_last();
    if ($error !== null && strpos($error['message'], 'Allowed memory size') !== false) {
      file_put_contents(MAGENTO_ROOT.'/var/log/oom.log', print_r(array($lastQueryString, $_REQUEST, $_SERVER, $error), true), FILE_APPEND);
      mail('info@examplecom', 'Server Memory Error', print_r(array($lastQueryString, $_REQUEST, $_SERVER, $error), true), 'Cc: mycolleague@example.com');
    }
}
register_shutdown_function('shutdownCapture');

and set these variables in the last reported function where the error occurs

+       global $lastQueryString;
+       $lastQueryString = $this->_stmt->queryString;
