Troubleshooting: Error "Unable to process document before allowed time" is returned

When generating the output for a large document, the following message may be returned:

This message indicates that the time required to process the output is longer than the timeout configured in the Output Generator for this output type.

To solve this issue:

Open the %OutputGenDir%/conf/client/outputtypes.xml file.
Locate the output type that is returning the error message.
For example:
```
<outputtype name="Dita2Pdf-IXIA" timeout="60000" system="false">
   <preprocessing>
      <preprocessor name="dita2pdf-ixia" />						
   </preprocessing>
   <renderer/>
</outputtype>
```
The timeout value is specified in milliseconds. In the default configuration, it's set to 60 seconds.

Increase the timeout value.

For example, increase it to 500 seconds:

<outputtype name="Dita2Pdf-IXIA" timeout="500000" system="false">
   <preprocessing>
      <preprocessor name="dita2pdf-ixia" />						
   </preprocessing>
   <renderer/>
</outputtype>

Save and close the file.
Restart the Output Generator and try again.

If the problem still occurs, set the timeout to a higher value and try again.
