np. The confusion is that there are 2 different values
that need to be set in DB_CONFIG and the resource cap
that one runs into is
        mutex_set_max
which should be ~10x (my rule of thumb) the other values.

Its kinda frustrating changing all the values to no effect
when one of the values (mutex_set_max) needs to be larger
than the others.
