[c3p0-users] C3P0Registry mbean is already registered - on redeploy

[Tom E. <ro...@te...>]

Hello,

I am using c3p0 v0.9.1.1 in a Tomcat 5.5.23 with Hibernate 3.2.2.
I do not have full access to the Tomcat, i.e. I can only copy a war
of my application to the webapps dir, causing a Tomcat redeploy.

When I do that, I get a lot of messages like the following:

2007-06-16 15:43:28,933 1232 
[ContainerBackgroundProcessor[StandardEngine[Catalina]]] WARN 
com.mchange.v2.c3p0.management.ActiveManagementCoordinator  - A 
C3P0Registry mbean is already registered. This probably means that an 
application using c3p0 was undeployed, but not all PooledDataSources 
were closed prior to undeployment. This may lead to resource leaks over 
time. Please take care to close all PooledDataSources.

I am sure that my Application calls (Hibernate) SessionFactory.close()
upon redeploy. That is all I am supposed to do, right ?

Now, is this an indication of a real problem (memory leak), or
should I just disable the JMX stuff, as I am not using it.

Thanks & Kind regards,
Tom.
