just use the -XX:+HeapDumpOnOutOfMemoryError and see what is causing the OOME

Hi all,

I am one of the committers and PMC member of the Apache OFBiz project (ofbiz.apache.org). Our project is using an embedded instance of Tomcat to run the web applications that compose the OFBiz suite of ERP applications.

A few weeks ago, with rev. 659490, we have upgraded Tomcat from to 5.5.23 to 6.0.16. Since then, we have noticed in some production server some "OutOfMemoryError: Java heap space" exceptions that make the instances pretty unstable after some time they are up. My suspect is that we are not creating the Tomcat instance in the right way, but I am not sure where is the error... and I'm not sure about the question I should ask here.
However, maybe someone of you could help with some advices or hints.

This is the code we used to create the instance of Tomcat 5.5.23 (that was working fine):

http://svn.apache.org/viewvc/ofbiz/trunk/framework/catalina/src/org/ofbiz/catalina/container/CatalinaContainer.java?revision=585848&view=markup

and this is the new code for 6.0.16:

http://svn.apache.org/viewvc/ofbiz/trunk/framework/catalina/src/org/ofbiz/catalina/container/CatalinaContainer.java?view=markup

Thanks so much,

Jacopo
