No cache blocks available for allocation.

Occurs on:  68 only.  This is an Abend error.

Meaning:  File server could not allocate any cache blocks because there
          was no free dynamic memory.

Cause:  File server does not have enough dynamic memory available to it
        to support the amount of disk storage that is connected to the
        server.  This error could also be generated as a result of a
        failure in high memory which would cause the file server to
        think that it has less memory installed.

Solution:  Test the memory to ensure that it is good.  If necessary, add
           more memory to the file server.
