Summary: JBoss Memory Leak

Initial Comment:
Operating System: Solaris 8
JDK Version: java version "1.3.1_01"

When employing the Minerva JDBC Local Transaction 
resource adaptor for connecting to the Polyhedra 
database, a memory leak will occur in JBoss when 
running the following test.

Test description:

We wrote a simple java client that sets a data field 
to a value, then to another value, and alternates 
forever.  For this test, four copies of this client 
were executed simultaneously and the system resources 
were observed and monitored using top.

We set JBoss' maximum heap size to 256m.  After 
starting the test clients, JBoss memory usage will 
continue to grow until it reaches its maximum heap 
size and then runs out of memory after about 1.5 hours.

It's important to NOTE that if you configure JBoss to 
instead employ the XA DataSourceLoader for Polyhedra, 
NO MEMORY LEAK WILL OCCUR when running the same test.
