Indexing a document fails with an error.

When indexing a document, warnings and a Failed to convert error are generated, which indicates that a content element file for the document could not be converted.

Symptoms

Initial warnings similar to the following appear in the p8_server_error.log file: Failed to convert <input-file> for object: {ZZZ} class: className export error:2050 request was retried 1 times out of 5 and will be retried again at a later time

When the retry completely fails, the following error appears:

Failed to convert <input-file> for object: {ZZZ} class: className export error:2050 request was retried 5 times out of 5 and no further retries will be attempted

Causes

The amount of time that is needed to convert a document's content element file from binary to text exceeds a configured maximum value.

Resolving the problem

Adjust the timeout value by changing the value of the Maximum lease interval property for text extraction. To use Administration Console for Content Platform Engine to access this property, open the Text Search Subsystem tab for the domain.
