Error description
This apar is to create a WTO message and perhaps take a KERNDUMP when the IPT is woken up due to a signal. This would signify to operators that SSL functionality is no longer available and they could recycle the CICS region potentially before it gets hung. The region would almost certainly need to be cancelled.

Problem summary
**************************************************************** * USERS AFFECTED: All. * **************************************************************** * PROBLEM DESCRIPTION: Abend 0C4 in DFHLEPTQ and CICS region * * becomes unresponsive. * **************************************************************** * RECOMMENDATION: * **************************************************************** CICS is running SSL processing and an unexpected abend occurs on one of the S8 TCBs which results in an abend on the initial pthread TCB for SSL. CICS has no recovery environment to intercept the abend of this TCB so no diagnostic message or dump information is produced.
Problem conclusion
DFHLEPTD has been changed to detect if a SIGCNCL is issued against the initial pthread TCB. A new message DFHAP1700 is issued to report the error. DFHLEPTD will then take a system dump with dump code KERNDUMP. CICS must be restarted to restore SSL functionality. The CICS Transaction Server for z/OS Version 5 Release 2 CICS Messages and Codes Vol 1 ( GC34728300 ) will be updated. In Chapter 4, new message DFHAP1700 will be added as follows:- DFHAP1700 APPLID An unexpected abend has occurred. CICS is unable to process any futher SSL requests. EXPLANATION: An unexpected signal, most likely a SIGCNCL signal, was received by the IPT TCB used for SSL processing. CICS is unable to handle any further SSL requests. SYSTEM ACTION: CICS attempts to take a system dump with dumpcode KERNDUMP. USER RESPONSE: Restart CICS. NOTE: This message cannot be changed with the message editing utility. DESTINATION: Console MODULE: DFHLEPTD
