# AppMap + GraphQL + Fiber Bug
This app replicates the bug reported at https://github.com/getappmap/appmap-ruby/issues/349.
## Conditions
- Using the appmap gem
- Using the latest graphql gem
- `config.active_support.isolation_level = :fiber` in application.rb
## Steps to reproduce
### 1. Prepare app
```bash
git clone [email protected]:coderberry/appmap-test-app-fiber-graphql.git
cd appmap-test-app-fiber-graphql
bin/setup
bin/rails db:migrate
bin/rails db:seed
```
### 2. Run the app
```bash
bin/rails s
```
### 3. Execute a query via GraphiQL
Open [http://locahost:3000/graphiql](http://localhost:3000/graphiql)) and execute the following query 5 times:
```graphql
query {
localCounts
}
```
### 4. Observe the hung fibers
Ensure you are viewing the Rails server logs and sumbmit the request a 6th time. The request will hang and you will see that the connection pool was not cleaned up.
Example:
