It may be necessary to adjust the timeout values that the DataSync Agent is using. You can do this using the attributes of <message_connection> with connection_request_timeout and connection_timeout

For example, you adjust these values to 120000 for 120 seconds. 

NOTE: this is only applicable if you are using https for the Agent.

Adjust the values in your agent.xml like so:

<?xml version="1.0" encoding="ISO-8859-1" standalone="no"?>
<config>
    <agent>
        <subscribe>
            <task>
                <task_name>timeout_example</task_name>
                <message_connection user="XXXX" password="XXX" connection_timeout="120000" connection_request_timeout="120000">https://example.perspectium.net</message_connection>
                .
                .
                .
            <task>
        <subscribe>
    </agent>
</config>
