Error description
When using FTPS, EZAFTPRU's setup_FTPOSTPR routine gets control. At offset x'192a' into EZAFTPRU, an attempt is made to store a halfword from Register 15 into the location addressed by Register 14, but Register 14's value at that point is zero, and therefore execution of the STH results in an attempt to store into low-core (inaccessible storage). This causes the abend0c4 reason code 4. KEYWORDS: FTPOSTPR 0C4 ABEND TLS
Local fix
Do not use TLS.
