APAR status
Closed as program error.
Error description
If IIDR CDC for z/OS is shutting down, and an Agent connection is concurrently terminating, it is possible to mis-reference the storage used to support the Agent's communication. This will cause a program check, which is trapped. However, the recovery logic is unable to associate the error with the Agent connection, so a diagnostic dump is produced.
Local fix
No local fix is available.
Problem summary
**************************************************************** * USERS AFFECTED: Users of IIDR CDC for z/OS who have Agent * * sessions that are frequently started and * * ended. * **************************************************************** * PROBLEM DESCRIPTION: If an Agent session is abandoned by the * * client concurrently with the IIDR CDC * * for z/OS address space being shut down, * * there is a possibility that an improper * * storage reference will occur, causing * * an ABEND S0C4. While this ABEND is * * trapped and recovered, the error cannot * * be associated with the abandoned Agent * * session, so a system dump is requested. * **************************************************************** * RECOMMENDATION: APPLY CORRECTIVE SERVICE * **************************************************************** Occasionally, a system dump may be requested if an Agent session has been abandoned concurrently with the address space ending.
Problem conclusion
Logic to associate the abandoned Agent connection with the storage resources has been corrected.
