Explanation
An attempt to allocate memory failed. The data server needs
more memory. The amount of memory that is available for use by the data server
is controlled by using the MESSAGE POOL SIZE parameter in the data server’s
Master Configuration Member. 

User response
See the MESSAGE POOL SIZE parameter definition in the
documentation for IBM® WebSphere® Classic Federation Server
for z/OS® for
instructions on how to use the MESSAGE POOL SIZE parameter and how it relates
to the total amount of memory that is available to the data server. The total
memory available is controlled by the data server’s REGION size.
