Problem summary
**************************************************************** * USERS AFFECTED: All CICS users. * **************************************************************** * PROBLEM DESCRIPTION: DFHSO0001 0C4 abend followed by * * multiple DFHSO0002 error messages. * **************************************************************** This problem only presents when SO Level 2 tracing is active. . A codepath exists in DFHSOCK where an SO 0201 trace entry is written during CLOSE_SOCKET_IN_POOL processing, this code is driven by the TIMER (TI) task. DFHSOCK requires an xm_txn_so_token value but this was unavailable from the TI task's KERNTASN entry. As a consequence, a null pointer was used by DFHSOCK causing the initial 0C4 and subsequent DFHSO0002 messages. Additional Keywords: MSGDFHSO0002 MSGDFHSO0001
Problem conclusion
DFHSOCK has been amended to preclude the aforementioned error.
