-----------------------------------------
Hi Tomaz,
One thing that you can check is whether the
ActivationConfigProperties maxSessions and maxMessagesPerSessions are both set
to 10. Actually the instanceLimit by default is 10 in geronimo for Mdbs and so
only 10 instances of the same MDB exist. If you are rasing the instance limit
to say 100 then raise both maxSessions and maxMessagesPerSessions (refer AMQ
http://activemq.apache.org/activation-spec-properties.html) such that they are
also 100 or <100.
Both should be same i.e maxSessions == maxMessagesPerSessions <= instanceLimit.
The instance limit can be set via the system property Default MDB
Container.InstanceLimit=125.
You can set it via the SystemPropertiesGbean or pass it during startup as a
system property.
eg: usage (modify the config.xml )
Change
<module name="org.apache.geronimo.configs/j2ee-server/2.0.1/car"/>
to
<module name="org.apache.geronimo.configs/j2ee-server/2.0.1/car">
<gbean gbeanInfo="org.apache.geronimo.system.properties.SystemProperties"
name="org.apache.geronimo.configs/j2ee-server/2.0.1/car?ServiceModule=org.apache.geronimo.configs/j2ee-server/2.0.1/car,j2eeType=GBean,name=CustomPropertiesGBean">
<attribute name="systemProperties">Default\ MDB\
Container.InstanceLimit=100</attribute>
</gbean>
</module>
Another thing to note is that you should provide enough threads to the RA.
Atleast 100 free threads for 100 parallel Mdbs. So its recommended to increase
the size of the server thread pool or provide a separate threadpool to the
resource adapter that your Mdb uses.

> MessageDrivenBean that listens on the Queue receive (and process) some
> messages and then stop receiving any new message until next module's restart.
> After restart a few next messages are delivered to MDB, and it stops again.
> Some additional information I put here
