+## Error: "too many open files"
+
+When running a Celestia bridge node, you may encounter an error in the
+logs similar to this:
+
+```bash
+Error while creating log file in valueLog.open error: while opening file: /opt/celestia/.celestia-bridge/data/003442.vlog error: open /opt/celestia/.celestia-bridge/data/003442.vlog: too many open files
+```
+
+This error indicates that the Celestia application is trying to open more
+files than the operating system's limit allows. To fix this, you will need
+to edit the Celestia bridge service file to increase the number of file
+descriptors that the service can open.
+
+1. Open the service file for editing:
+
+```bash
+nano /etc/systemd/system/celestia-bridge.service
+```
+
+2. Modify the `LimitNOFILE` parameter:
+
+In the service file, find the `LimitNOFILE` parameter under the
+`[Service]` section and set its value to `1400000`. It should look like this:
+
+```ini
+[Service]
+...
+LimitNOFILE=1400000
+...
+```
+
+:::tip NOTE
+Be cautious when increasing file descriptor limits. Setting this value too
+high might affect system performance. Ensure the value is appropriate
+for your system's capabilities.
+:::
+
+3. Reload daemon and restart bridge service:
+
+```bash
+sudo systemctl daemon-reload
+```
+
+```bash
+sudo systemctl restart celestia-bridge
+```
