[OFBiz] Users - DB2 strange behaviour

Javrishvili, Giorgi (Key-Work)
Hi everybody!

I need to compare query results from 2 different DBs. For that I have
implemented one service that does following:
It goes to the specified directory, reads sql files and executes each on
the appropriate DB. One DB in sql server(no problems with that) and the
other  - IBM DB2. And here is a problem(I even don't know how to
formulate it better): When the service executes query for DB2 - it
causes java.lang.OutOfMemoryError. But it happens only ON FIRST CALL OF
SERVICE!!! I mean, when I call in once more next time(and once more...)
it's working fine - no errors anymore.
So, has anyone had the same problem?

Not sure if it helps, but here is all the info that is needed, I think:

Here are entries for DS and appropriate helper in entityengine.xml:
       
    <delegator name="default" entity-model-reader="main"
entity-group-reader="main" entity-eca-reader="main"
distributed-cache-clear-enabled="false">
        <group-map group-name="org.ofbiz"
datasource-name="AGS_OFBiz_DS"/>
        <group-map group-name="de.keywork.extranet"
datasource-name="AGS_EXTRANET_DS"/>
    </delegator>
. . . .

    <datasource name="AGS_EXTRANET_DS"
            helper-class="org.ofbiz.entity.datasource.GenericHelperDAO"
            schema-name="ags"
            field-type-name="db2"
            check-on-start="true"
            add-missing-on-start="true"
            join-style="ansi"
            use-fk-initially-deferred="false">
        <read-data reader-name="seed"/>
        <read-data reader-name="demo"/>
        <read-data reader-name="ext"/>
       
        <inline-jdbc
                jdbc-driver="COM.ibm.db2.jdbc.app.DB2Driver"
                jdbc-uri="jdbc:db2:D_AGS_EX"
                jdbc-username="extranet"
                jdbc-password="xf6pw!m12"
                pool-minsize="2"
                pool-maxsize="20"/>
    </datasource>

Here are messages and exceptions during execution:
