[rules-users] OutOfMemory with BRMS 4.0.3

[sophie.ramel at tudor.lu]

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,

Sophie

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 ?
>PS : http://jira.jboss.com/jira/browse/JBRULES-1325

Regards
/Mikael
