If CA ACF2 PTF SO14108 is active on a system running IBM MFA an Abend S0C4 may occur in SAFO6MFA+x'166C'
The solution to this abend is SO14631.
Unfortunately SO14631 was published before the possiblity of the abend was known,
therefore SO14108 could not be set as being PE'd and superceded by SO14631
