CAUSE

Legal production gets in a hanging state if one of the file types does not have an image production format assigned. This caused the production to hang as it did not have an action for these files. The output settings in Legal Production are set to produce images and text only while other files were excluded from those output types.

RESOLUTION

The documents need at least one output action or the production will hang. By specifying the system (in the Natives tab of the Legal Production wizard) to produce the files in a native format, a valid action step is assigned to these files. This will allow the production to complete successfully.
