Description

I've registered a Symfony command in TYPO3 v9 to import products. After 1000 products I've experienced a memory usage of >500MB.

Thanks to XDebug, I've figured out what causes the memory leak: It's the \TYPO3\CMS\Adminpanel\Log\InMemoryLogWriter registred in adminpanel extension.

When I put this to my extension's ext_localconf.php:

if (PHP_SAPI === 'cli') {
    unset($GLOBALS['TYPO3_CONF_VARS']['LOG']['writerConfiguration'][\TYPO3\CMS\Core\Log\LogLevel::DEBUG]);
}

the memory usage during full import stays below 50M.
