Hi @DANANZ M1. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Based on the information provided in the knowledge sources, I can offer some insights and suggestions regarding memory leaks in Nuxt applications: 1. Memory leaks can occur due to various reasons in Nuxt applications. One common cause is improperly handling server-side operations that cannot be garbage collected, such as misusing plugins or creating intervals that are not cleaned up Stack Overflow (https://stackoverflow.com/questions/78606574). 2. The watchHandle array you mentioned is not specifically referenced in the provided knowledge sources. However, it could be related to watchers or hooks that are not properly disposed of when components or routes change. 3. To trace down where the watchHandle is triggered, you can try the following approaches: a. Use the debugging tools provided by Nuxt. You can enable sourcemaps in your Nuxt configuration to make debugging easier Nuxt Debugging Guide (https://nuxt.com/docs/guide/going-further/debugging#sourcemaps):

   export default defineNuxtConfig({
     sourcemap: {
       server: true,
       client: true
     }
   })

   export default defineNuxtConfig({
     sourcemap: {
       server: true,
       client: true
     }
   })

b. Use Node inspector to debug server-side code Nuxt Debugging Guide (https://nuxt.com/docs/guide/going-further/debugging#debugging-with-node-inspector):

   nuxi dev --inspect

   nuxi dev --inspect

c. Set up debugging in your IDE, such as VS Code or JetBrains IDEs, using the configurations provided in the Nuxt documentation Nuxt Debugging Guide (https://nuxt.com/docs/guide/going-further/debugging#debugging-in-your-ide). 4. Pay attention to how you're using state management. Ensure that you're following best practices, such as not defining reactive state outside of <script setup> or setup() function Nuxt State Management (https://nuxt.com/docs/getting-started/state-management#best-practices). 5. If you're using watchers or hooks, make sure they are properly cleaned up. Recent updates to Nuxt have addressed issues with accumulating watchers and hooks Nuxt GitHub PR (https://github.com/nuxt/nuxt/pull/27571). 6. Consider using the dispose() method provided by storage utilities to ensure there are no open handles left when closing your application Unstorage Guide (https://unstorage.unjs.io/guide#dispose). 7. If you're unable to identify the source of the leak, consider creating a minimal reproduction of the issue and seeking help from the Nuxt community Nuxt Bug Reporting Guide (https://nuxt.com/docs/community/reporting-bugs). Remember, tracking down memory leaks can be challenging. If you're still unable to identify the source, you might need to create a minimal reproduction of the issue to get more specific help from the Nuxt community or developers. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
