I've passed through this TID 10018669 and haven't found anything about the
number of free directory entries which is 2-3% in all of our 4 cache
volumes. There is two set parameters for allocated directory cache buffers
(minimum and maximum), so I've set the minimum to 1000 and increased maximum
from suggested 4000 to 10000 in steps of 500.

However, the number of allocated directory cache buffers didn't fall bellow
10000 and I'm not sure if I can increase it any more. At the same time, the
number of free directory entries didn't increase above 2-3% in all of our 4
cache volumes, so do I have to:

a) continue increasing the maximum directory cache buffers, or
b) do something else to increase the number of free directory entries?
