I have seen all these replies and have RTFM those messages. Ok, on what z/OS 
and DB2 versions are you?


What have changed? From replies I see possibilities and guesses:

FA suddenly decides to do investigation.
First time combination of all these loadlibs in JOBLIB (or STEPLIB or LINKLIST)?
JCL Change?
Blocksize of first loadlib in JOBLIB changed?
WHAT Changed? APF, LLA, LPALIST LINKLST, CSV, Extents, Exits....?
Fetch from APF and a copy is obtained somewhere?

You said: No IPL, no z/OS maintenance, but were there any maintanance or 
application (DB2?) changes done?

You also said about recovering from HSM, good, that is one culprit which is 
weeded out. I would also do that immediately.


My guess: Are there other modules with the same name hidden in the JOBLIB (or 
STEPLIB or LINKLIST)?

What happens if you turn OFF the FA during that batch job run?

Indeed - "The module *is* 32760 while the PDS *is* 19069" will certainly break 
your things.

Can you perhaps do a IEBCOPY with reblocking?
