I have never used the embedded server so please ignore my ignorance, and feel free to ignore my post if it makes no sense. Is the server embedded within a Java application? If so, change the heap size for the Java application. Since it is all in one JVM... Is the server embedded within a C/C++/??? application? What API call is used to load the server? I know that the standard API function used to load the JVM has a parameter that takes JVM options, and you can add the heap sizes to that parameter.
