Cause

The failure happens due to time-out(30 min by default) of an internal session.

Fix

As a workaround, try to increase the timeout value. The value is hardcoded in META-INF/spring/newAgentContext.xml in the following jar files:

[newAgentContext.xml]
<bean id="sessionTimeout" class="java.lang.Long">
    <constructor-arg type="long" value="7200000"/>
</bean>
