Hi

I've got a similar issue except that in my case, processes started from java simply
reset entries in my database. 
I have only one process available. The first step in this process is a human task.

If I start 2 process instances from the jBPM console, both process instances appear in the
"Process Overview" tab and they also appear in the database (I'm persisting
PROCESSINSTANCEINFO, PROCESSINSTANCELOG, SESSIONINFO, VARIABLEINSTANCELOG, WORKITEMINFO
and NODEINSTANCELOG in a H2 DB).

If I start the same process from the java code, my 2 previous process instances disappear
(both from the console and the database which is consistent) and get replaced by the new
process instance.
If I start another process instance from the java code, it replaces the previous one so
that I can never have more than 2 process instances started from my java code.

Here is my java code:

        EntityManagerFactory emf = Persistence.createEntityManagerFactory(
"org.jbpm.persistence.jpa" );
        Environment env = KnowledgeBaseFactory.newEnvironment();
        env.set(EnvironmentName.ENTITY_MANAGER_FACTORY, emf);
        env.set(EnvironmentName.TRANSACTION_MANAGER,
TransactionManagerServices.getTransactionManager());
        env.set( EnvironmentName.GLOBALS, new MapGlobalResolver() );

        KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
        kbuilder.add(ResourceFactory.newClassPathResource(ACCESS_WORKFLOW_FILE),
ResourceType.BPMN2 );
        KnowledgeBase kbase = kbuilder.newKnowledgeBase();
        StatefulKnowledgeSession ksession =
JPAKnowledgeService.newStatefulKnowledgeSession(kbase, null, env);

        JPAWorkingMemoryDbLogger dbLogger = new JPAWorkingMemoryDbLogger(ksession);
        KnowledgeRuntimeLogger logger =
KnowledgeRuntimeLoggerFactory.newFileLogger(ksession, "test");
        ksession.getWorkItemManager().registerWorkItemHandler("Human Task", new
CommandBasedWSHumanTaskHandler(ksession));

        ksession.startProcess(ACCESS_WORKFLOW_ID, new HashMap()); 

        dbLogger.dispose();
        logger.close();

Also I forgot to mention it but I'm deploying jBPM 5.1 on Tomcat 6 and I'm not
using Guvnor but simply a directory specified in "-Djbpm.console.directory".

I've also noted some strange behaviour where my process instances also seem to be
reset everytime I restart tomcat. The entries remain in the DB after I shutdown Tomcat and
they also remain in it once I've restarted Tomcat and logged in the jBPM console again
but the moment I go to the "Process Overview" tab and jBPM reloads the process
definition, all process instances disappear from my DB.

I think that I'm missing something important here but I don't know what.
Any help would be greatly appreciated
