Prestashop: Fatal error, probably memory corruption

[zozizozu]

Describe the bug
On the client side it's an error 500, the php log show "PHP Fatal error: Uncaught PrestaShop\PrestaShop\Core\Foundation\IoC\Exception: This doesn't seem to be a class name: PrestaShop\PrestaShop\Adapter\Prlduct\PriceCalculator. in _rootdir__\src\Core\Foundation\IoC\Container.php:101"
As you can see, it search for a namespace call "Prlduct" , instead of "Product".

More over, i also notice a "PHP Fatal error: Uncaught Error: Call to undefined method Symfony\Component\Yaml\Parser::moveToPreviousLine() in _rootdir__\vendor\symfony\symfony\src\Symfony\Component\Yaml\Parser.php:743" , and of course, as you know, the method exists .

I'm not sure those errors are linked but i feel the cache is involve in some memory troubles / stack overflow ...

The version i use ( 1.7.5.1 ) is an upgrade from 1.6, where everything work find untill we put the site online, so i guess the number of access is also involve ...

To Reproduce
Unfortunaly i can not reproduce this error, it seems to happend some times, for some clients ...
Restating http server and clearing cache solve the problem for a few time ( 24/48 h )

Screenshots

Additionnal information
PrestaShop version: 1.7.5.1
PHP version: 7.2.18 x64
Apache version: 2.4.39 x64

Hi @zozizozu,

Could you please try to clear cache manually by deleting all the folder into var/cache (prod & dev).
Thanks to check and feedback.

[zozizozu]

Yes, i did clear the cache, and as i said, "clearing cache solve the problem for a few time ( 24/48 h )"

[khouloudbelguith]

@zozizozu, thanks for your feedback.

After removal of cache try with those commands:

php -d memory_limit=-1 ./bin/console cache:clear
php -d memory_limit=-1 ./bin/console cache:clear --env=prod

Thanks to check & feedback

[zozizozu]

Actually i first did a php console , then the rm -rf
Now server is running since 24h, i let you know the next time i get this error

@zozizozu, thanks!
Waiting for your feedback.

Hi, it looks my server is still online without no troubles, sorry °)
I forgot to mention that i've increased RAM and CPU, maybe it helps ovoiding those troubles ...
Also forgot to said that server is running on Windows Server 2012

@khouloudbelguith , Ooops, it seams i only have to talk about it : i now have an error 500 accessing the backoffice ( of course, all those require failed files exists ) :

PHP Warning: require(_ROOT_DIR_\vendor\composer/../symfony/polyfill-ctype/bootstrap.php): failed to open stream: No such file or directory in _ROOT_DIR_\vendor\composerautoload_real.php on line 61

Then i tried "php bin\console cache:clear && php bin\console cache:clear --env prod" that returns :

Warning: Uncaught Symfony\Component\Debug\Exception\ContextErrorException: Warning: require_once(_ROOT_DIR_\modules\statscatalog\vendoq\composer/autoload_static.php): failed to open stream: No such file or directory in _ROOT_DIR_\modules\statscatalog\vendor\composerautoload_real.php:28

I finally remove manually var\cache , remove vendor 's directory and replace by the original vendor from the archieve, and it looks ok

@zozizozu, thanks for these clarifications.

[zozizozu]

@khouloudbelguith, Thanks to you for paying attention.
Are you sure you want to let this issue close ? I feel all these errors are linked to the cache management.
Parsing old logs files, i found some

PHP Fatal error: Uncaught Error: Class 'Symfony\Component\Yaml\Yaml' not found in ...\src\Core\Addon\Theme\Theme.php:41

and

PHP Fatal error: Class 'Symfony\Component\HttpKernel\Kernel' not found in ...app\AppKernel.php on line 33

I guess that if core's file are not found, and existing functions are undefined, it's probably some kind of stack overflow.

Hi, I finally find out what was generate these strange behaviour : i have set opcache.enable to 0 and since 6 days, i have no errors.
Thanks again
