In a multitenant (CDB (container database)) Oracle Golden Gate environment, the following error occurs in the alert log:

ORA-00600: internal error code, arguments: [KGHFRE3], [0x2DA438FA8], [], [], [], [], [], [], [], [], [], []

 

The Call Stack Trace in the associated incident trace file shows:

 <- ktcCommitTxn <- ktdcmt <- k2lcom <- k2send <- xctctl <- xctCommitTxn
  <- ktcPopAutonomousFrame_ext <- kwqmnpartition <- kwqmnich <- kwqmnichcb <- kpdbSwitch

    <- ssthrdmain <- main

 

The same incident trace file also shows a heap dump such as the following:
