Use After-image Stall (-aistall) to suspend database activity if all AI files are filled. Then wait until the next AI file is backed up and marked empty and send this message to the database log file:

Can’t switch to after-image extent filename it is full. (3775)
Backup ai extent and mark it as empty (3776) 

This way you can empty an AI file instead of shutting down the database.

When using after-image (AI) files, you monitor the status of the files to ensure that you do not attempt to reuse an unavailable file. If all the AI files are filled and Progress cannot switch to an empty one, by default the database shuts down. See the Progress Database Administration Guide and Reference for information on using the after imaging feature.
