Problem

Adams applications report an error with the following message:

Server did not respond within the specified timeout interval.

Verbose logging in the Adams application and in the database reveals that a query is sent to the database but never returns.

The error is not linked to a specific query or type of query. Nor is it linked to load on the database server.
