Symptoms

ORA-600 [kcbw_get_bh_1] and/or ORA-7445 [kcbw_dump_granule()+775] errors are raised.
This can also show up as ORA-7445 [kcbw_get_le] and ORA-7445 [kcbw_get_sim] errors.

The stack dump will be similar to:

<- kcbw_get_bh <- kcbw_dump_granule <- kmgs_dump_quiesce_list <- kmgs_create_request <- kmgs_immediate_req <- ksmasg <- kghnospc <- kghalf <- kksLoadChild <- kxsGetRuntimeLock <- kksfbc <- opiexe <- opiodr <- rpidrus <- skgmstack <- rpidru <- rpiswu2 <- rpidrv <- rpiexe <- kmgsb_get_advice <- kmgsb_gather_statistics <- kmgsb_tune <- tics <- ksb_run_managed_action <- ksbcti <- ion <- ksbabs <- kebm_mmon_main <- ksbrdp <- opirip <- opidrv <- sou2o <- opimai_real <- main <- start

In either case, the call stack will show module kcbw_dump_quiesce_list called from ksmg_create_request.
