Hi Romain!
We increased the PoolMaxSize setting for the JmsConnectionFactory:
Tomee.xml:
[...]
<Resource id="JmsResourceAdapter" type="ActiveMQResourceAdapter">
BrokerXmlConfig
broker:(tcp://localhost:61616)?persistent=true&useJmx=false
ServerUrl = failover:(tcp://localhost:61616)?randomize=false
DataSource JmsDS
</Resource>
<Resource id="JmsConnectionFactory" type="javax.jms.ConnectionFactory">
ResourceAdapter = JmsResourceAdapter
PoolMaxSize = 200
ConnectionMaxIdleMinutes = 0
TransactionSupport = local
</Resource>
[...]
Best regards,
Thomas

Hi
did you set JmsResourceAdapter.MaximumPoolSize to something higher than 30
or JmsResourceAdapter to something <= 0?
