1. Re: Memory leak
Is this a real memory leak, or is it a sign you are actually consuming resource for your load? If it is just resource consumption, have you tried giving your JVM more heap space via -Xmx160m or whatever is appropriate as per standard Java options? If this is not the issue, have you researched issues with your JDBC driver and possible associated memory leaks, or other related issues?

2. Re: Memory leak
Check your jdom.jar (jboss/lib). JBoss should use a higher version than 1.0 beta8 (check its info.xml file in the META-INF), since this version is causing memory leaks.
I think this was fixed with JBoss 3.2.1.. don't ask me for the 3.0.x. version ;-)

4. Re: Memory leak
It is a real leak - after few hours I fet out of memory exception. I am not using JDBC. I use JNI - I load a dll which do the SQL job

5. Re: Memory leak
This is really difficult. Asking the ejb spec will tell you:
the enterprise bean must not attempt to load a native library.
You are handling with external resources the container doesn't know about. Be careful, since you are probably causing these leaks by yourself!
