ORA-600 [17119] errors and ORA-7445 (Doc ID 413802.1)

Last updated on APRIL 21, 2010

Applies to:

Oracle Server - Enterprise Edition - Version: 10.2.0.2 and later   [Release: 10.2 and later ]
Information in this document applies to any platform.

Symptoms

Intermittent memory corruptions, usually leading to instance failure. The errors generally start with ORA-600 [17119], followed by other errors such as ORA-7445 [kghidmp_new], or ORA-600 [17105] and ORA-7445 [kghfrx].

 

Some traces show that the heap descriptor and name have been overwritten:

********** Internal heap ERROR 17119 addr=0000000000000000 *********
******************************************************
HEAP DUMP heap name=" �p�" desc=c00000010cd570e8
extent sz=0xc0000001 alt=0 het=0 rec=0 flg=0 opc=0
parent=0001000000000000 owner=00b38f0000000151 nex=c00000010cd57540
xsz=0xffffffffc0000001
EXTENT 0 addr=c00000010cd570d0
.
in addition to other corruptions within the memory dump.

The stack trace is similar to:

kghpih <- kghfex <- kghfrx <- kghfrunp <- kghfnd <- kghalo <- kghgex <- kghalf <- kksLoadChild <- kxsGetRuntimeLocak <- kksfbc <- kkspsc0 <- kksParseCursor

Some traces don't have the heap header overwritten but show overwrites within the heap memory. kghfrunp is in the Stack.
