Shrinking the database buffer cache on versions prior to 10g Release 2 (10.2) to a value less than the current database buffer cache size may lead to instance crashing and generating the following error:

ORA-00600: internal error code, arguments: [kcbbxsv_2]

The call stack will be similar to following:

ksedmp <- ksfdmp <- kgerinv <- kgeasnmierr <- kcbassertb <- kcbbxsv <- kcbbwpng <- kcbbdrv <- ksbabs <- ksbrdp <- opirip <- opidrv <- sou2o <- main <- start
