What is Laravel advanced memory leak prevention in long-running processes like queues and Octane?

Memory leak prevention ensures long-running Laravel processes do not accumulate unused objects or references over time.

In queue workers and Octane, Laravel stays in memory across multiple requests or jobs, unlike traditional PHP lifecycle. This creates risk of memory leaks due to static properties, unresolved closures, large collections, or retained service container bindings. Proper handling involves clearing variables, avoiding global state, resetting singletons when needed, and using job-level isolation. Monitoring memory usage and restarting workers periodically is also essential.
