Configure remote asynchronous EJB method results

Use this task to set the maximum number of unclaimed results for a remote asynchronous EJB method call.

When a remote asynchronous EJB method is called, the server must save the results of the remote method invocation until the client claims the results using the Future.get method. If the client never claims the result, unclaimed results can accumulate in the server and use memory. To avoid using too much memory, the server limits the number of unclaimed results to 1000 by default. If the number of unclaimed results approaches or exceeds the limit, the server issues the CNTR0328W warning.
