# SqlException – Timeout abgelaufen

Beheben Sie den Fehler „SqlException timeout expired“ in Remote Desktop Manager, indem Sie die Funktion „Bereinigen“ verwenden, um Verlaufs- und Protokolldaten aus der Datenbank zu entfernen.

`SqlException - timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.`

Dieser Fehler tritt auf, wenn eine SQL-Operation zu lange bis zum Abschluss benötigt, häufig weil der Server nicht reagiert oder die Abfrage die konfigurierte Timeout-Dauer überschreitet.

### Lösung

Große Mengen an Verlaufs- oder Protokolldaten in der Datenbank können zu langsamen Antwortzeiten führen. Verwenden Sie die Funktion [Bereinigen](/rdm/de/ribbon-menu-bar/administration.md), um unnötige Daten zu entfernen und die Leistung zu verbessern.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.devolutions.net/rdm/de/knowledge-base/troubleshooting-articles/sqlexception-timeout-expired.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
