[jailed shell]mmap() failed: [12] Cannot allocate memory

Luana Premoli
Hi, I am trying to install Laravel on a shared server using JailedShell access. But the error below is shown: mmap() failed: [12] Cannot allocate memory mmap() failed: [12] Cannot allocate memory Fatal error: Out of memory (allocated 809508864) (tried to allocate 4096 bytes) in phar:///home1/appbac20/hg/composer.phar/src/Composer/DependencyResolver/RuleSetGenerator.php on line 129 The commands executed are: [CODE=bash]appbac20@mydomain3294209.com.brr [~/hg]# php -v PHP 7.2.31 (cli) (built: May 19 2020 20:03:28) ( NTS ) Copyright (c) 1997-2018 The PHP Group Zend Engine v3.2.0, Copyright (c) 1998-2018 Zend Technologies with the ionCube PHP Loader + ionCube24 v10.3.9, Copyright (c) 2002-2019, by ionCube Ltd. appbac20@mydomain3294209.com.brr [~/hg]# appbac20@mydomain3294209.com.brr [~/hg]# appbac20@mydomain3294209.com.brr [~/hg]# curl -sS https://getcomposer.org/installer | php All settings correct for using Composer Downloading...

    What is the global memory limit for the version of PHP you're running? You can find this at WHM>>Software>>MultiPHP INI Manger or via the CLI with the following (while logged in as the user): php -i |grep memory_limit
    You can change it with the whmapi1 function php_ini_set_directives function (ensure you're logged in as the root user) whmapi1 php_ini_set_directives directive-1=memory_limit%3A128m version=ea-php74
    replace the value for memory_limit to whatever you want to set it and ea-php74 with the ea-phpXX version you're using

    That doesn't necessarily mean that it will always work though. The other client may be using php memory limit in a different way you really can't compare accounts like that unless they have the exact same configuration, on the exact same server, with the exact same amount of traffic at the same time - which is nearly impossible.

    Hi, I created this topic just to try to find out what's wrong with the first customer. What I meant by the previous answer is that it is not by changing a global server directive that the problem will be solved, because if this were the case, I believe that all customers of the same server would have the problem reported, which is not the case. case. The error occurs with a specific user.

    Is "Shell Fork Bomb Protection" active?
    0
  • SamuelM
    Hello @Luana Premoli Can you please clarify whether you are running the commands from a standalone SSH client like Putty on Windows, or iTerm on a Mac? Or are you using the terminal emulator feature inside cPanel itself? Additionally, can you please let us know which version of cPanel is in use on the server where you receive the error message? If you are using the terminal emulator feature inside cPanel itself, it is likely that the "Fatal error: Out of memory (allocated 809508864) (tried to allocate 4096 bytes)" error occurs because the cPanel service itself imposes a maximum memory limit of 4096 bytes: -bash-4.2# grep maxmem /var/cpanel/cpanel.config maxmem=4096
    If this seems like a reasonable explanation for the error you're observing, I would suggest you try logging in with a standalone SSH client to resolve the problem. However, I am only speculating at this point based on the information available thus far. If my hypothesis doesn't apply in this case, please let us know and we will review further.

    Hi, With "Shell Fork Bomb Protection" disabled, it works normally, but this is a shared server and we don't want to leave this option turned off. I am logging in through Putty with Jailed Shell user and password for a computer with Windows 10 Pro 64 bit OS. appbac20@mydomain3294209.com.brr [~]# grep maxmem /var/cpanel/cpanel.config maxmem=4096 appbac20@mydomain3294209.com.brr [~]#

    Hello again @Luana Premoli Thank you for confirming that information. The Shell Fork Bomb Protection implements specific limits which are the reason the Composer CLI commands are failing. While researching this I found the following forum posts I would like to refer you to. Here is a basic overview and explanation about how user limits are implemented with the Jailshell system: Note that modifying these limits is not supported, and any changes you make will likely be overwritten when toggling Jailshell off or on again. However, hopefully these posts and the information discussed within will point you in the right direction. You may also want to consider enabling Normal Shell access for users that require unrestricted access. Best regards
