Error description
You receive an SOS above the line followed by a series of abends. The first abend is DFHRZ0001, DFHRZ0001 An abend (code 0C4/AKEA) has occurred at offset X'2EF6' in module DFHRZTA. The function takes place in rzrs_move_bytes_proc. Prior to that, the code obtains the storage for the data area. Due to the system being SOS, the storage allocation fails and a null pointer is returned. This failure condition is not checked, and leads to abend0c4 when an attempt to move data to the area addressed by the invalid pointer. The issue is similar to PK62944.

Problem summary
**************************************************************** * USERS AFFECTED: All. * **************************************************************** * PROBLEM DESCRIPTION: ABEND0C4 during Request Streams * * processing. * **************************************************************** * RECOMMENDATION: * **************************************************************** The CICS system is under storage stress and has entered an SOS state several times. During this period a Webservice that requires the use of Request Streams to communicate between tasks or systems is running. DFHRZTA in procedure rzrs_send_reply_part requests storage for various control and data areas but due to the system being storage constrained one of the getmains fails and a null pointer is returned. As there is no check for this condition, when an attempt is made to move data to the area addressed by the invalid pointer an ABEND0C4 occurs.

Problem conclusion
Temporary fix
FIX AVAILABLE BY PTF ONLY
Comments
Module DFHRZTA has been amended to check the return code from a getmain before using the storage pointer.
