• Ultra Tasks become disabled. Ultra Task configuration includes a setting for the maximum number of times a Pipeline can fail to start before the Snaplex disables the Ultra Task. During development or troubleshooting, you might want to disable this feature or increase the number. 

• A Pipeline will not start. A pipeline processes a document multiple times. If the FeedMaster does not receive an acknowledgment that a document was processed, it can be retried. By default, the document may be retried up to five times. You can change this in Snaplex configuration as described in Configuring Snaplex Retries.

• Unhandled errors. To troubleshoot errors and failures in an Ultra Pipeline it is a good practice to implement error and exception handling. When the Pipeline handles errors and exceptions, the Snaplex will not automatically disable the Ultra Task.
