Abend U0322 can occur while transforming a large file.
Determine the value of the MAXCPU= parameter on the X2YY statement in your ESFPARM file.
If you do not have it coded, then you are using the default value, which is 60 CPU seconds.
Increase the MAXCPU value to something high enough to enable the transform process to complete, for example, 600 (seconds), and then restart Spool.
