Because we have 0 free allocated file descriptor on both serers:
cupserver1$ cat file-nr
1400  0  102667

cupserver2$ cat file-nr
1380  0  102667

I'm not sure if this alone will improve performance but I'm looking at
every possible scenario.

More than 30 is easily surpassed for our app servers during peak times.
