JRun4 out of memory error (heap)

[allen_tremain]

I am having a problem with JRun4 update 7 running out of memory. I am sure it
is just a setting somewhere but all I can find are settings with JRun/CF
together on the net. I am running Jrun4 and IIS6 without Cold Fusion. I have
created a datasource to a mysql database. I am using SnappMx to build a Flash
GUI using flash remoting. The initial test I am retrieving 95000 records. When
this goes into production I will limit the return results. I am just testing
the performance and memory allocation. The memory never get's release until I
get a java exception OutOfMemory (heap).

Here are my JVM settings:
-----------------------------------
java.home=C:\\System\\Java\\jdk1.6.0_03

java.args=-server -DJINTEGRA_NATIVE_MODE -DJINTEGRA_PREFETCH_ENUMS -Xmx512m
-Xms256m -Xss256k -XX:NewSize=64m -Dsun.io.useCanonCaches=false
-XX:+DisableExplicitGC -XX:PermSize=32m -XX:MaxPermSize=128m -XX:+UseParNewGC
-XX:-UseParallelGC

Here is my datasource settings:
--------------------------------------------

<data-source>
<dbname>remote_master</dbname>
<driver>com.mysql.jdbc.Driver</driver>
<url>jdbc:mysql://127.0.0.1:3306/remote_master</url>

<transaction-timeout>20</transaction-timeout>
<cache-enabled>false</cache-enabled>
<cache-size>5</cache-size>
<cache-refresh-interval>30</cache-refresh-interval>
<jndi-name>remote_master</jndi-name>
<poolname>Pool</poolname>
<minimum-size>0</minimum-size>
<maximum-size>2147483647</maximum-size>
<user-timeout>20</user-timeout>
<skimmer-frequency>420</skimmer-frequency>
<shrink-by>5</shrink-by>
<maximum-soft>true</maximum-soft>
<debugging>false</debugging>
<disable-pooling>true</disable-pooling>
<description />
<isolation-level>READ_COMMITTED</isolation-level>
</data-source>

I am really stuck on this one. If you need any other settings let me know.
Thanks,
Allen
