# Troubleshooting

This is a solution to problems that frequently occur when installing and operating the log service. If any additional problems arise, please contact us.

### When the master/data nodes of the log service do not start properly during installation <a href="#install-error" id="install-error"></a>

<details>

<summary>ERROR: [1] bootstrap checks failed [1]: max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]</summary>

The following error occurs because during the bootstrap check process, if the max\_map\_count value is less than 262,144, it is not executed for stability.

Therefore, connect to the relevant node, enter the following command, and then restart.

```sh
/$ vi /etc/sysctl.conf

# record
vm.max_map_count=262144

# apply
/$ sysctl -p
```

### When the fluent-bit container does not work properly

<details>

<summary>[error] could not open configuration file, aborting.</summary>

This log is an error that occurred because the fluent-bit configuration file mount information is different. Please check the configuration file name and location carefully before distributing.
