The timeout period elapsed prior to completion of the operation or the server is not responding.` This error occurs when an SQL operation takes too long to complete, often because the server is unresponsive or the query exceeds the configured timeout period. ### Solution Large amounts of historical or log data in the database can cause slow responses. Use the [Clean up](/rdm/ribbon-menu-bar/administration.md) feature to prune unnecessary data and improve performance. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.devolutions.net/rdm/knowledge-base/troubleshooting-articles/sqlexception-timeout-expired.md?ask=&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.
