nsslapd-dbcachesize

This performance tuning related attribute specifies database cache size. Note that
this is neither the index cache nor the entry cache. If you activate automatic cache
resizing, you override this attribute, by replacing these values with its own
guessed values at a later stage of the server startup.
If you attempt to set a value that is not a number or is too big for a 32-bit signed
integer you will receive an
additional error information explaining the problem.
