Error in Spring integration - not processing further messages

I have the following configuration 

<int:chain input-channel="requestsChannel">
    <int:splitter ref="aBean" method="aMethod" />
    <!-- routing to the appropriate processing channels -->
    <int:recipient-list-router default-output-channel="feedRequestChannel">
        <int:recipient channel="whateverRequestChannel" selector-expression="payload.source == 'whatever'"/>
    </int:recipient-list-router>
</int:chain>

<int-http:outbound-gateway request-channel="feedRequestChannel" reply-channel="feedResponseChannel"
    url="{source}"
    http-method="GET" expected-response-type="java.lang.String">
    <int-http:uri-variable name="source" expression="payload.getSource()" />
</int-http:outbound-gateway>

Now I get the error

... 57 more

which is not a problem. The aMethod returns a collection of two objects, one going through feedRequestChannel and second through whateverRequestChannel. But when I get the above error the second object is not processed anymore.

Is there any config so that I can ignore errors?

Since <splitter> produces several messages to send, it would be good, if its output-channel will some thread-shift (executor, queue etc.).

Having that the error for the first message won't impact the second one.

From other side, if you need sigle thread (one by one sending/processing), you can play a bit with <request-handler-advice-chain> for each of <outbound-gateway> to strangle error using ExpressionEvaluatingRequestHandlerAdvice with trapException = true
