When working on many PDF files in Acrobat Reader DC extensions, ensure that the following time-out values are set appropriately to prevent jobs from timing out and failing:
Document Disposal Timeout
This value can be set in administration console. Click Settings > Core System Settings > Configurations and specify a value for Default Document Disposal Timeout.
User Manager AEM forms Timeout: This value can be set by editing the config.xml file. In administration console, click Settings > User Management > Configuration > Import and export configuration files, and then click Export. Open the exported config.xml file and edit the following lines:
<entry key=“assertionValidityInMinutes” value=“600”/><entry%20key=?lang=en"SessionTimeout" value=“600”/>
Save and then import the config.xml file back into administration console.
Application Server Session Timeout: This value can be set on the application server. For more information, see the documentation provided with your application server.
