CKM02352E PROCESSING FOR uuuuuuuu HAS BEEN TERMINATED

Explanation
While unloading data for a data set, a fatal error caused BACKUP to stop
processing the cluster "uuuuuuuuuu".

User response
This error was detected by the Catalog Fast Reader Module and reported
by the Error Summary Module. Numerous CKM341xxI messages accompany this message.
If "NOEXAMINE" was not coded and EXAMINE did not detect errors, it is possible
that the cluster was successfully backed up. To determine if this the case,
using IDCAMS, execute EXAMINE explicitly:

//AMS EXEC PGM=IDCAMS IDC01710I DATA COMPONENT CONTAINS nnn RECORDS 

//SYSPRINT DD SYSOUT=*

EXAMINE NAME(...)DTEST

EXAMINE will issue several messages. Find the message

Compare the nnn value to the total records unloaded by BACKUP which is
indicated in the message
