DUCC - Work Item Queue Time Management

[reshu.agarwal]

Hi,
I am facing a problem in DUCC that some documents were shown in queue 
but did not get processed. In Job, work item list shows a particular 
work item's status "queued" and queueing time is "4115 seconds".

I want to set queueing time of work item not more then 1 minute. What is 
the reason for the same? Is there any method to solve this? How can I 
set maximum queueing time for work item?

Thanks in advance.

Reshu.
