** What does "unresponsive child" error message mean? --------------------------------------------- Like any system, FreeRADIUS provides error messages to inform administrators of problems within the FreeRADIUS server itself. Sometimes however, error messages that are logged by FreeRADIUS are actually reporting an indication that something is wrong with one of the connected systems. A common cause of some of these errors is an unexpectedly slow database. The unresponsive child message is essentially a timeout error. It means that a request was sent to the database, and the database hasn’t responded within a set time limit. Most database queries should happen instantaneously from the perspective of a human being, which means much less than one second. In contrast, the unresponsive child message is produced by FreeRADIUS after about 30 seconds! That is, FreeRADIUS is letting you know that it hasn’t heard back from the database in a very long time. This long time to respond indicates a major problem with the database.
