I've seen this before and had to locate the CPIEF12 error. It took a bit but in the end
I had to reconfigure the Service Agent. It was a several step process as I recall but
relatively easy.

Perhaps a place to start:

Where I work we have one LPAR getting daily CPIEF12 messages like:

Service Agent was unable to send a message to user ???????/ .
Service Agent was unable to send a message to user ???/?%? ??.
Service Agent was unable to send a message to user ???/??????.

from job QSJSENDER. Data area QSRVAGT/QS9USERS is set to a blank list, all EBCDIC x'40's, as it is on other LPARs where QSJSENDER jobs are running successfully without getting CPIEF12 messages. Does anyone know what might be causing this?

Try prompting CHGSRVAGTA and actually change a user name and see if that makes a difference.

I checked out
select data_area_value, HEX(data_area_value) from
table(qsys2.data_area_info(DATA_AREA_LIBRARY => 'QSRVAGT',

And x'40' blanks are used as the filler.

A casual glance didn't seem to care about CCSID.

A search for that error message had only 3 hits. One was some site which felt a need to list all IBM error messages themselves. The other two were
1 - 7.3 upgrade instructions admonishing you to put on PTF's after the upgrade but didn't mention that message specifically.
2 - An IBM site listing 'recommended ptfs' including service agent but not that specific error message.
Weird. Does even google say if you can't find the specific message then get current on PTF's and try again?
