Error while creating outbound Native MQ adapter Service

Question

I have created a BPEL process to produce text message into an MQ using native MQ adapter. Here is my oc4j-ra
<connector-factory location="eis/MQ/MQSeriesAdapter" connector-name="MQSeriesAdapter">
<config-property name="hostName" value="192.168.50.57"/>
<config-property name="portNumber" value="1414"/>
<config-property name="queueManagerName" value="QM.CIDC.01"/>
<config-property name="channelName" value="TO.EMTRX.CORP.CIDC01"/>
<config-property name="userID" value=""/>
<config-property name="password" value=""/>
<config-property name="clientEncoding" value=""/>
<config-property name="hostOSType" value=""/>
<config-property name="xATransaction" value="false"/>
<connection-pooling use="private">
<property name="waitTimeout" value="300" />
<property name="scheme" value="fixed_wait" />
<property name="maxConnections" value="50" />
<property name="minConnections" value="0" />
</connection-pooling>
<security-config use="none">
</security-config>
</connector-factory>
I am able to initiate this process successfully only up to 50 times (maxConnections value). After that if i try to run the process i am getting an error called
Adapter Framework unable to create outbound JCA connection.
file:/opt/webapps/oracle/product/SOAAS_10.1.3/bpel/domains/default/tmp/.bpel_CEATestMQPut_1.0_501b2921d076cc40796fba3556d34b4f.tmp/ENQUE.wsdl
[ Enqueue   _ptt::Enqueue(root) ] - : The Adapter Framework was unable to establish an outbound JCA connection due to the following issue:
javax.resource.spi.Resou rceAllocationException: Unable to allocate new connection - pool is full and timed out waiting for a connection to be freed up.
Now i want to know is there any way to free up the connection pool. So that i do not need to change the maxConnections property.
Appreciate if any one can help.
