Problem description

I’m encountering a memory leak when using Filament with Laravel Octane and FrankenPHP.
Memory usage steadily grows across requests and is never released until the worker is restarted.

This happens on a completely clean Laravel + Filament installation, without any custom code, plugins, or configuration.
It occurs on any route, though /admin/login is the simplest way to reproduce.

Expected behavior

• Memory usage should remain stable across requests when using long-lived workers
• Filament should not retain request-scoped state between requests
• Octane workers should be safely reusable for hundreds or thousands of requests

With --max-requests=1, memory usage remains stable, which indicates that the leak is related to long-lived workers.

Steps to reproduce

1. Create a fresh Laravel installation
2. Install Filament (latest version)
3. Create an admin user: php artisan filament:user
4. Install and configure Laravel Octane with FrankenPHP
5. Start Octane with:

• Baseline (no leak): php artisan octane:start --server=frankenphp --max-requests=1
• Problematic (memory growth): php artisan octane:start --server=frankenphp --max-requests=500

6. Send 100 HTTP requests to the same endpoint (example):GET /admin/login (issue is reproducible with any route)
7. Observe memory usage:

• With --max-requests=1 → memory stays stable
• With --max-requests=500 → memory grows steadily, logs show 14 MB → 100 MB

8. laravel.log

Please help me by confirming

1. If you can reproduce the same with Filament v4 instead of 5
2. If you can reproduce the same with just Livewire 4 installed and not Filament
3. If you can reproduce on other Octane drivers like Roadrunner

Please help me by confirming

1. If you can reproduce the same with Filament v4 instead of 5
2. If you can reproduce the same with just Livewire 4 installed and not Filament
3. If you can reproduce on other Octane drivers like Roadrunner

Thanks for the questions. Here are the results.

Filament v4:

Tested with the same setup and ~1000 requests.
Memory usage remains stable.

• FrankenPHP: ~10–18 MB
• RoadRunner: ~42–46 MB

Filament v5:

• Memory usage grows steadily across requests on both FrankenPHP and RoadRunner.

Livewire 4 only:

• Not tested yet.

Other Octane drivers (RoadRunner):

• Reproduced. Memory growth is slower than with FrankenPHP, but still unbounded.

This strongly suggests a regression introduced in Filament v5 affecting long-lived Octane workers.

[danharrin]

Given the very minimal differences between Filament 4 and 5, this sounds like it could be a Livewire issue.

[antonian99work]

Given the very minimal differences between Filament 4 and 5, this sounds like it could be a Livewire issue.

Thanks for the suggestion. I’ve tested this thoroughly:

• Plain Livewire 4 only (no Filament, no Volt) with ~1000 requests: memory remains stable (~8–12 MB) on both FrankenPHP and RoadRunner.
• Filament v4 with the same setup: memory stable.
• Filament v5 with the same setup: memory steadily grows across requests.

It’s possible that the memory leak is related to Filament v5 rather than Livewire itself. Please let me know if you’d like me to run any additional tests or provide logs to help investigate further.

[eboboshka]

Damn! That's why I sometimes get a 500 error. It happened after updating to Filament 5.
UP!

[oanqa]

maybe related to this livewire/livewire#9756

[danharrin]

Thanks @oanqa, I think that is almost certainly the problem. Seems like a fix is being worked on in livewire/livewire#9763, so closing this.
