Re: [rules-users] OutOfMemory with BRMS 4.0.3

2008-01-23 Thread Michael Neale 
Ok so yes the error is on the brms web app. The agent will poll the  
brms , so that may be causing it.


So, could you try to run the brms without the agent hitting it and see  
if it happens ( will narrow it down massively)? Also, what tomcat, jdk  
and I

Os version?

Hello michael,


Is the rule agent running on a separate server to the brms?

The initial configuration was:
- BRMS in tomcat 5.5
- server with RuleAgent in Jboss AS 3.2.8

But now I moved to this configuration:
- server with RuleAgent in Jboss AS 3.2.8 (unchanged)
- BRMS is also in the same jboss instance

And in both cases I have the problem.


Is the rule agent actually running when the error happens?

No I don't think so.
I don't have any exception before I try to go to a web page (either  
of the
BRMS, or of my other server in Jboss when the BRMS is in the same  
jboss
instance), and then I get OufOfMemoryError: Java heap space. The  
RuleAgent
is only instantiated when I send a specific request to my server  
(and I'm

not even sure it was called once before the last crash).


Also that is an old version  of jboss as?
yes, it's Jboss application server 3.2.8 (I think it is the last and  
only

one in the 3.x series that works with JDK 1.5): I need to use an older
version because of other compatibility issues of my server, but  
since I
had exactly the same problem with Tomcat, I'm beginning to think it  
may

not be linked to the server version ...?

Sophie

Thanks sophie. A few more questions to narrow this down. Is the rule
agent running on a separate server to the brms? Is the rule agent
actually running when the error happens? Also that is an old version
of jboss as?

I guess the rest depends on your answers to the above.

Let me know.

Hello again,

When you get back to work if you could provide more info it would be

great.
What kind of info do you need?
Here is what is done in my server code, to fire the rules:

Properties props=new Properties();
props.setProperty(newInstance, false);
props.setProperty(url, packageURL);
props.setProperty(localCacheDir, cacheDir);
props.setProperty(poll, 30);
props.setProperty(name, Agent-+pid);
RuleAgent agent = RuleAgent.newRuleAgent(props);
RuleBase rb = agent.getRuleBase();
workingMemory=ruleBase.newStatefulSession();

and then we insert all objects in the working memory with wm.insert
(o);,
but recursively in order for all the objects to be directly
accessible in
rules (We've got a hierarchic structure, an XML file transformed in
Java
by JAXB, so the insert method tests the accessor methods of the
object and
is called recursively on the accessors' results, before inserting the
object).

then we call:
workingMemory.fireAllRules();
[...interprate results...]
workingMemory.dispose();


Best regards,

Sophie

If the agent is running then it polls the brms. So that could be one

2008-01-23 Thread sophie . ramel 
Well, I'm pretty sure no agent hit the brms on my server last week, it's a 
development server and I'm currently the only one using it, so the agent 
wasn't instantiated (or perhaps I tried it once or twice at the beginning 
of the week, to check that it worked, but that's all). 

The tomcat version was tomcat 5.5 (but here again, the error also occurs 
in Jboss 3.2.8), jdk is jdk 1.5.0 , and the system is an old Red Hat 7.2.

Sophie

 In 4.0.3, there is a memory leak with the use of WorkingMemoryLogger.
 Maybe it's that ?

 The server has nearly no access - it's a development server which is not a
 lot used at the moment - and there are only a few rules, for tests, so I
 really don't understand this error. I'm using java 1.5.0 on a linux
 server.

 The BRMS is accessed by web, to create and deploy the rules, and queried
 from another tool (on the same machine but in another server: in JBoss),
 to insert data in a workingMemory and execute the rules from the deployed
 package URL. I call the dispose() method on the StatefulSession at the end
 of the query (but this shouldn't be linked to this error, since this is in
 JBoss and the OutOfMemory occurs in tomcat...).

 Any idea?
 Thanks,

 Sophie

If you have any more details  - and confidential, feel free to send them to
me direct (currently I am working on some stress tests to see if I can make
it happen more quickly ;)

 Hi Sophie - how is the jboss runtime server querying this? via the rule
 agent (and a URL)?

 just trying to work out what the usage pattern is so we can reproduce it.

[rules-users] OutOfMemory with BRMS 4.0.3

Hello, 

I am using Drools BRMS 4.0.3 with tomcat 5.5.25, and I get OutOfMemory

Re: [rules-users] OutOfMemory with BRMS 4.0.3

2008-01-10 Thread Mikael Larsson 

Hi!

Are you using the WorkingMemoryLogger?
Here is some information from a previous mail thread (Drools 4.02 or 
4.03 memory leak?) on this list:



In 4.0.3, there is a memory leak with the use of WorkingMemoryLogger.
Maybe it's that ?

Hi, 

No, I don't use the WorkingMemoryLogger from my client classes in Jboss. 
And I don't know if the BRMS uses it, I suppose not otherwise more people 
would have the problem?

best regards,

Re: [rules-users] OutOfMemory with BRMS 4.0.3

2008-01-10 Thread sophie . ramel 
No, I haven't, because initially I wanted it to be deployed in an 
environment distinct from my client classes, which are in jboss 
application server (but 3.2.8 for compatibility reasons...). 
But I can try: do you think my problem may be linked to tomcat ?

best regards,

Sophie
