__Environment info:__

* System info: Linux 5.14.15-200.fc34.x86_64 x86_64
* InfluxDB version: `2.0.9`
* Other relevant environment details: `podman`

__Config:__
Copy any non-default config values here or attach the full config as a gist or file.

__Logs:__
Include snippet of errors in log.

__Performance:__
Generate profiles with the following commands for bugs related to performance, locking, out of memory (OOM), etc.

```sh
# Commands should be run when the bug is actively happening.
# Note: This command will run for ~30 seconds.
curl -o profiles.tar.gz "http://localhost:8086/debug/pprof/all?cpu=30s"
iostat -xd 1 30 > iostat.txt
# Attach the `profiles.tar.gz` and `iostat.txt` output files.
```

Start by reproducing the crash with `podman pull influx:latest` and `podman run influx:latest` on InfluxDB 2.0.9. Read `bolt/bbolt.go`, especially `Client.initialize` and `Client.Open`, alongside the stack trace through `cmd/influxd/launcher/launcher.go`. Done means InfluxDB launches without the `page 20 already freed` panic.
