[rules-users] OutOfMemory with BRMS 4.0.3

[sophie.ramel at tudor.lu]

Hi Michael,

I'm not at my company these days so I cannot check or make further tests.
But yes, we use a rule agent and an URL to query the rule.
And it happens after 1-2 days whether we use the system or not, it doesn't
seem to make any difference.

however, I'll check when returning, but I think it still worked after a few
days, now that I have moved the BRMS to the Jboss 3.2.3 app server.

thanks for trying to help me!

Sophie

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.

Hello,

I am using Drools BRMS 4.0.3 with tomcat 5.5.25, and I get OutOfMemory
exceptions in tomcat regularly.

I recently changed the java option of tomcat to add "-Xmx512m", but it
only resulted in taking a little more time before crashing (3 days,
instead of 1 before).
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
