Hi all,
When I was running a ESB proxy service which transforms a huge xml message
using smooks mediator, following exceptions were thrown.
java.lang.OutOfMemoryError: GC overhead limit exceeded

Below given is my synapse sonfiguration and this worked in ESB 4.5.0.
<definitions xmlns="http://ws.apache.org/ns/synapse";>
<localEntry key="smooks-key"
src="file:repository/samples/resources/smooks/smooks-config-802.xml"/>
<proxy name="StockQuoteProxy" transports="vfs">
<!--CHANGE-->
<parameter
name="transport.vfs.FileURI">file:///home/lakmali/dev/test/smooks/in</parameter>
<parameter

<parameter name="transport.vfs.FileNamePattern">.*\.xml</parameter>
<parameter name="transport.PollInterval">5</parameter>

<target>
<inSequence>
<smooks config-key="smooks-key">
<input type="xml"/>
<output type="xml"/>
</smooks>
</inSequence>
</target>
</proxy>
</definitions>
Is any configuration needed to avoid this problem?
Thanks,
Lakmali
