Unexpected Memory Leak in PHP 8.2 with Symfony Console Commands
I've spent hours debugging this and Quick question that's been bugging me - I'm working on a project and hit a roadblock. I'm working with a seemingly trivial scenario with memory management while executing Symfony console commands in a PHP 8.2 application. I've noticed that when I run a specific command, the memory usage spikes significantly and does not seem to release after the command completes. For instance, using the command: ```bash php bin/console app:my-command ``` It starts at around 20MB but can grow to over 500MB during execution, depending on the size of the data being processed. I’ve tried executing with `php -d memory_limit=512M` just to ensure it doesn't run out of memory, but I’m concerned about this growth. The command processes data from a large array of objects: ```php public function execute(InputInterface $input, OutputInterface $output) { $largeDataSet = $this->fetchLargeDataSet(); // fetches an array of around 10,000 objects foreach ($largeDataSet as $data) { // process each object $this->processData($data); } } ``` In `processData`, I’m using several third-party libraries for handling JSON transformations and database operations. I suspect that something in there is leading to a memory leak, possibly through static variables or closures that are retaining references. I've also confirmed that I'm unsetting all large variables after use like so: ```php unset($data); ``` I've run this in a local development environment as well as on our staging server, both running PHP 8.2 and Symfony 5.4. I monitored the memory usage using the Symfony profiler but found no obvious leaks in the profiler output. I need to seem to identify if it's an scenario with Symfony, the libraries I'm using, or perhaps even PHP itself. Any suggestions on how to effectively debug this memory scenario or best practices for managing memory in such scenarios would be greatly appreciated! This is part of a larger CLI tool I'm building. Thanks in advance! Is there a better approach? This is part of a larger desktop app I'm building. Thanks for taking the time to read this! Any pointers in the right direction?
