You can find `opensearch.yml` in `/usr/share/opensearch/config/opensearch.yml` (Docker) or `/etc/opensearch/opensearch.yml` (most Linux distributions) on each node.
You don't mark settings in `opensearch.yml` as persistent or transient, and settings use the flat form:
```yml
cluster.name: my-application
action.auto_create_index: true
compatibility.override_main_response_version: true
```
The demo configuration includes a number of settings for the security plugin that you should modify before using OpenSearch for a production workload. To learn more, see [Security]({{site.url}}{{site.baseurl}}/security-plugin/).

This page contains a list of common issues and workarounds.
## Java error during startup
You might see `[ERROR][c.a.o.s.s.t.OpenSearchSecuritySSLNettyTransport] [opensearch-node1] SSL Problem Insufficient buffer remaining for AEAD cipher fragment (2). Needs to be more than tag size (16)` when starting OpenSearch. This problem is a [known issue with Java](https://bugs.openjdk.java.net/browse/JDK-8221218) and doesn't affect the operation of the cluster.
## OpenSearch Dashboards fails to start
If you encounter the error `FATAL Error: Request Timeout after 30000ms` during startup, try running OpenSearch Dashboards on a more powerful machine. We recommend four CPU cores and 8 GB of RAM.
## Multi-tenancy issues in OpenSearch Dashboards
If you're testing multiple users in OpenSearch Dashboards and encounter unexpected changes in tenant, use Google Chrome in an Incognito window or Firefox in a Private window.
## Expired certificates
If your certificates have expired, you might receive the following error or something similar:
```
ERROR org.opensearch.security.ssl.transport.SecuritySSLNettyTransport - Exception during establishing a SSL connection: javax.net.ssl.SSLHandshakeException: PKIX path validation failed: java.security.cert.CertPathValidatorException: validity check failed
Caused by: java.security.cert.CertificateExpiredException: NotAfter: Thu Sep 16 11:27:55 PDT 2021
```
To check the expiration date for a certificate, run this command:
```bash
openssl x509 -enddate -noout -in <certificate>
```
## Encryption at rest
The operating system for each OpenSearch node handles encryption of data at rest. To enable encryption at rest in most Linux distributions, use the `cryptsetup` command:
