Subject Facing java.lang.OutOfMemoryError:GC overhead limit exceeded when using Camel Aggregator
Date Fri, 29 May 2015 10:34:44 GMT
I am facing a java.lang.OutOfMemoryError: GC overhead limit exceeded for a
file which is generated using aggreagation. Below is my route


    <route id="sendToFileRoute">
        <from uri="direct:sendToFile" />
        <choice>
            <when>
                
                <simple>${property.FileName} != 'LIVEFEED'</simple>
                <to uri="bean:intermediateFileProcessor?method=processSNE"
/>
                <camel:aggregate completionSize="300"
strategyRef="aggrMessToFile" forceCompletionOnStop="true"
completionTimeout="5000" >
                    <camel:correlationExpression>
                       
<camel:simple>${property.stageFileName}</camel:simple>
                    </camel:correlationExpression>
                <camel:to
uri="file://{{intermediate.dir.path}}?fileExist=Append&amp;fileName=$simple{property.stageFileName}"
/>
                </camel:aggregate>
            </when>
        </choice>
    </route>


The file generated is something like -
V2_10.246.84.69_INI_TIMER_US_20150528_102000514_32.xml

Below is the error log
