Hi there, First of all I have got to say that I tried the following : Jboss 4.0.5 Jboss 4.2.2 jbrms 4.0.2 jbrms 4.0.3 jbrms 4.0.4 jbrms 4.0.x (SVN first days of march) I tried all the possible combinations between those above. Then let me show u my scenario. I have got a client which sends a "contract id" to a queue. Then an MDB is invoked to pass that "id" to an deserializer which builds up a "contract object". Once I have got the "contract object" I pass it to Drools in order to perform some reasoning over it and to get back a reply from the engine. _Let me show you how my application "Uses drools":_ *public* *static* *synchronized* *final* WorkingMemoryEventManager getSession(*boolean* statefull) { /log/.info("Getting Agent Singleton from: "+Thread./currentThread/().getName()); *if* ( /ruleagent/ == *null* ) { *try* { /ruleagent/ = /BRMS_RuleAgent/(); } *catch* (Exception e) { e.printStackTrace(); } } *if* (statefull){ /rulebase/ = /ruleagent/.getRuleBase(); /session/ = /rulebase/.newStatefulSession(); } *else* { /rulebase/ = /ruleagent/.getRuleBase(); /session/ = /rulebase/.newStatelessSession(); } /log/.info("Releasing Agent Singleton from: "+Thread./currentThread/().getName()); *return* /session/; } As You can see I can get either a statefull session or a stateless one in a thread-safe way. Let's say i always get a stateless one. _The Ruleagent is used as follows:_ *private* *static* RuleAgent BRMS_RuleAgent() *throws* Exception { RuleAgent agent = RuleAgent./newRuleAgent/( "/brmsdeployedrules.properties"); //add the package to a rulebase (deploy the rule package). *return* agent; } *I configured the ruleagent to "newInstance=true", with a refresh of 5 secs and localcachedir=.* So, everytime the contract comes to be evaluated i call a /getSession/() in order to load the rulebase. In EVERY AServer and with EACH JBRMS version, the the RuleAgent seems can't connect to the rulebase and so it simply loads the rules from the cache. Furthermore if I change the jbrms rules, the RuleAgent really DOES NOT CARE about it and we know that after 5 seconds it should AUTOMATICALLY refresh the rulebase but at the end IT DOES NOT DO ANYTHING! _After a while I also get back the following error message:_ /11:17:06,219 ERROR [[/drools-jbrms]] Exception while dispatching incoming RPC call/ 11:17:09,997 ERROR [[GWTRemotingServlet]] Servlet.service() for servlet GWTRemotingServlet threw exc eption java.lang.OutOfMemoryError: PermGen space 11:17:10,005 INFO [Log4jService$URLWatchTimerTask] Configuring from URL: resource:jboss-log4j.xml 11:17:10,890 ERROR [CoyoteAdapter] An exception or error occurred in the container during the reques t processing *And after it the AS REALLY CRASHES and one more of my hairs BECOMES WHITE !!!! :( :(* _To be more clear let me show you what happens if I execute drools_ _with jboss 405 and jbrms 404, without the ruleagent cache activated:_ /11:50:18,275 INFO [DroolsServiceProvider] Getting Agent Singleton from: JMS SessionPool Worker-0 11:50:18,331 ERROR [STDERR] RuleAgent(RuleAgentMassi) INFO (Sat Aug 04 11:50:18 CEST 2007): Configuring with newInstance=true, secondsToRefresh=5 11:50:18,336 ERROR [STDERR] RuleAgent(RuleAgentMassi) INFO (Sat Aug 04 11:50:18 CEST 2007): Configuring package provider : URLScanner monitoring URLs: /// <http://127.0.0.1:8080/drools-jbrms/org.drools.br>/http://127.0.0.1:808... <http://127.0.0.1:8080/drools-jbrms/org.drools.brms.JBRMS/package/com.spyd... //http://127.0.0.1:8080/drools-jbrms/org.drools//. brms.JBRMS/package/com.spyd.rules.ConsolidateData/ConsolidateData /// <http://127.0.0.1:8080/drools-jbrms>/http://127.0.0.1:8080/droolsjbrms <http://127.0.0.1:8080/droolsjbrms/org.drools.brms.JBRMS/package/com.spyd.... 11:50:19,840 INFO [STDOUT] PackageName: com.spyd.rules.initAction 11:50:19,841 INFO [STDOUT] PackageVersion: initAction 11:50:19,841 INFO [STDOUT] PackageIsLatest: false *11:50:20,559 ERROR [STDERR] RuleAgent(RuleAgentMassi) EXCEPTION (Sat Aug 04 11:50:20 CEST 2007): org .drools.base.dataproviders.MVELDataProvider; local class incompatible: stream classdesc serialVersio nUID = 6980593313545470049, local class serialVersionUID = 1901006343031798173.

I mean, it is the exact copy which worked perfectly until* *last week.....Why the hell it does not work now???* I have always got the same OS (VISTA) and i did not update any sensible component of my pc.
