Error description

  • UNEXPECTED IPC MESSAGES RECEIVED FOLLOWING PROCESS
    TERMINATION CAUSE EC TO ABEND REPEATEDLY
    

Local fix

Problem summary

  • When the EC recieved an IPC message from an unknown process, it
    logs diagnostic information and generates an FFST. When this
    change was introduced in 5318 there was a coding error that
    results in a NULL pointer in some cases, which causes the EC to
    repeatedly abend
    

Problem conclusion

  • Change the diagnostic code to remove the use of the pointer if
    it is null.
    

Temporary fix

  • Restart the queue manager
