Fatal Error: Allowed Memory Size of 134217728 Bytes Exhausted (CodeIgniter + XML-RPC)

Question

I have a bunch of client point of sale (POS) systems that periodically send new sales data to one centralized database, which stores the data into one big database for repor

Answer 1

You can properly fix this by changing memory_limit on fastcgi/fpm:

$vim /etc/php5/fpm/php.ini

Change memory, like from 128 to 512, see below

; Maximum amount of memory a script may consume (128 MB)
; http://php.net/memory-limit
memory_limit = 128M

to

; Maximum amount of memory a script may consume (128 MB)
; http://php.net/memory-limit
memory_limit = 512M

When adding 22.5 million records into an array with array_push I kept getting "memory exhausted" fatal errors at around 20M records using 4G as the memory limit in file php.ini. To fix this, I added the statement

$old = ini_set('memory_limit', '8192M');

at the top of the file. Now everything is working fine. I do not know if PHP has a memory leak. That is not my job, nor do I care. I just have to get my job done, and this worked.

The program is very simple:

$fh = fopen($myfile);
while (!feof($fh)) {
    array_push($file, stripslashes(fgets($fh)));
}
fclose($fh);

The fatal error points to line 3 until I boosted the memory limit, which eliminated the error.

Answer 3

Rather than changing the memory_limit value in your php.ini file, if there's a part of your code that could use a lot of memory, you could remove the memory_limit before that section runs, and then replace it after.

$limit = ini_get('memory_limit');
ini_set('memory_limit', -1);
// ... do heavy stuff
ini_set('memory_limit', $limit);

I spent two dyas looking a solution for this and I figured out that this was cause in a call with PDO when I called

$stmt->bindParam(":PERIOD", $period); 

and the variables period was an

empty string ''

So this issue could have multiple root cause, my advice to you is that try a trial and error or a bisection method for a root cause finding, delete code and the try to search what is the line code that is failing

Update: I also faced this error with the method $pdo->query() I used $pdo->prepare() and worked well, so, while I had

$sql = "SELECT * FROM COURSE_DETAILS where ACTIVE = 1 AND COURSE_DETAILS_ID = $id";
$stmt = getConnection()->query($sql);
$courseDetails = $stmt->fetchAll(PDO::FETCH_ASSOC)

then i changed this to

$sql = "SELECT * FROM COURSE_DETAILS where ACTIVE = 1 AND COURSE_DETAILS_ID = ?";
$stmt = getConnection()->prepare($sql);
$stmt->execute(array($id)); 

and magically the memory error dissapeared!

When I removed the following lines from my code, all worked OK!

set_include_path(get_include_path() . get_include_path() . '/phpseclib');
include_once('Net/SSH2.php');
include_once('Net/SFTP.php');

These lines were included in every file I was running. When running the files one by one, all worked OK, but when running all files together I got the memory leak issue. Somehow the "include_once" is not including things once, or I am doing something wrong...

Answer 6

Running the script like this (cron case for example): php5 /pathToScript/info.php produces the same error.

The correct way: php5 -cli /pathToScript/info.php
