PH timeout Server Configuration Option
Applies To: SQL Server 2016
Use the PH timeout option to specify the time, in seconds, that the full-text protocol handler should wait to connect to a database before timing out. The default value is 60 seconds. Increase the ph timeout value when connection attempts are timing out due to temporary network issues.
The full-text protocol handler is hosted in the filter daemon host and is used to fetch from SQL Server the data to be full-text indexed. For more information about full-text search components, see Full-Text Search.
When attempting to fetch a data row, if the protocol handler cannot connect to SQL Server within the specified time, it reports a time-out error for that row. The full-text gatherer will retry the row later. For more information about the full-text gatherer, see Populate Full-Text Indexes.
