executionTimeout defines the maximum period allowed for a request to execute. This value is represented in seconds, and the default is 90 seconds If users frequently see Request timed out messages, or if they are uploading large documents, the executionTimeout value may need to be increased for proper processing. Document uploading may also exceed the timeout period due to heavy disk group activity.
Note:
If you intend to export PCL documents to PDF, the executionTimeout value must be set to a larger number than 300. The recommended value is 86000. This allows an export to succeed without timing out.
