What happened?

Description

When a constant introspection request is made, memory leakage occurs.

Steps to Reproduce

The simplest way is to open Apollo GraphQL Studio and enable Auto Update in the Connection settings. The sandbox will start sending an introspection request every second, and at that moment, you can observe a rapid increase in RAM usage. After disabling auto-update, the memory gradually clears up.

Here's the config.json, and I’ve already provided the router configuration.
