ORA-07445: exception encountered: core dump [$cold_kspptval()+7073] [SIGSEGV] [Address not mapped to object] [0x9FFFFFFFBF7803E8] [] []

signalled by the mman process, followed by instance failure:

ORA-00822: MMAN process terminated with error
Instance terminated by PMON, pid = 18561

The trace file for the ORA-7445 [$cold_kspptval] contains the stack trace:

$cold_kspptval <- $cold_kspset <- ksp_bg_param_update <- kmgs_update_param_auto <- kmgsdrv <- ksbabs <- ksbrdp <- opirip <- opidrv <- sou2o


This can be caused by running any program, such as datapump, which requires the streams pool to be defined. The instance must be using an spfile.
