When you have "Allow Multiple Datastreams" attribute enabled in a backup job, a backup job will be divided into multiple jobs so that all can run concurrently. NBU determines a job can be divided into multiple jobs or not depending on the backup selections. 

Below are some technotes referring to catalog backup failures and resolutions:

Explanation of Catalog parent and child jobs:

http://www.symantec.com/docs/TECH61108

When an online catalog backup is run, it normally generates four jobs on NetBackup 6.5 (and later:(
a parent job,
a child job for copying database files to a staging directory,
a child job for NetBackup relational database tables,
and a child job for catalog images and configuration data.
