you can try activating the KnowledgeRuntimeLogger to see what is happening inside the knowledge session.. you will find the answers there..
If you can share what objects are you inserting inside the parameter maps and how your rules looks like we can help..
Also if your process define the variables that you are inserting as parameters..

I create a knowledge base in the typical fashion.  I construct a knowledge
builder and add my drl and rf files, then instantiate my knowledge base.

I build my parameter map and then start the process using my knowledge base.

       StatefulKnowledgeSession session =
processKnowledgeBase.newStatefulKnowledgeSession();

       ProcessInstance processInstance = session.startProcess(name, parameterMap);

       session.insert(processInstance);
       session.fireAllRules();

I assume this is pretty typical code from what I have read.
