Hi there,

Thanks for bringing this up, and we’re sorry to hear you’re facing this issue. To help us better understand what’s going on, could you please provide a bit more detail?

Specifically:

- What’s your hardware/environment setup?
- Which version of Dragonfly are you running?
- Is there any chance that a client (e.g., a local CLI/SDK or any connected application) could have issued a command like `FLUSHALL`?

This does sound unusual, so we’d need more context to investigate further. If this is your production instance, feel free to join our [Discord server](https://discord.gg/HsPjXGVH85), and we may be able to connect you with an engineer for additional support. But we’ll definitely need more information to move forward.

For example, hypothetically, if you are running Dragonfly on a public cloud on the default port without authentication, that could be very dangerous, and hackers can easily issue destructive commands.

Whatever the issue could be, if you still have the Dragonfly instance, **the output of the `INFO ALL` command** would be a good starting point for us to help with the situation.

From the `Commandstats` section, we can see that the `FLUSHALL` command was called twice.

Is there any possibility that an application service calls this command upon restart? (i.e., some example code snippets perform a flush to ensure a clean environment.)

Thanks @joezhou_df. Now working, It was authentication issue only.

Glad we figured it out! Easy fix—and please double-check those settings to avoid it happening again.

I’ll go ahead and update the post title to reflect the solution. If you have any other questions or run into anything else, feel free to ask!

As an additional side note, you may consider renaming/disabling some commands like `FLUSHALL` in your production instance using configs like `--rename_command` or `--restricted_commands`.
