Symptoms

The database crashes after the following errors:

ORA-07445: exception encountered: core dump [kgldtin:7285[kgl.c]] [SIGSEGV] [Address not mapped to object] [0x000000000] [] []
ORA-07445: exception encountered: core dump [kglobcl:2690[kgl2.c]] [SIGSEGV] [Address not mapped to object] [0x000000000] [] []

 

The call stack will look similar to the following:

kgldtin kgldti kkdlgob qcsfgob qcsprfro qcspqb kkmdrv opiSem opiprs kksald rpiswu2 kkslod  kglobld kglobpn kglpim kglpin kksfbc kkspsc0 opiosq0 . . .

 

The PROCESS STATE section in the tracefile may show a latch is being held.  For example:

holding 455b66948 Child library cache level=5 child#=1
Location from where latch is held: kgldti: 2child:
Context saved from call: 0
state=busy

 

Changes

This problem is introduced in 9.2.0.6 by the fix for unpublished Bug:3749490.  Any database with a one-off or merge patch containing the fix for unpublished Bug:3749490 can be affected.
