Data Extract Widget doesn't work sometimes

Greeting everyone,

I am currently using the Data Extract Widget and have exposed its corresponding geoprocessing tool. I works as intended when I select a reasonably small area with the selection tools the widget makes available. Executing the tool executes the process and outputs the zip file. Unfortunately, whenever I select a larger region when I download the file to my local computer...it doesn't store it. I have preset the configuration of the geoprocessing tool to output a shape file rather than a file geodatabase. I don't know what is the issue.

I presume it's because the dataset is too big or something of the sort. I have taken a look at the jobs folder in the arcgis directory and it seems that the resulting zip files is 0Kb.

I don't know why is it that it works for a small selection and not a larger one...Does this warrant the use of an ArcSDE? I just want to make sure I have tweaked all things possible before proceeding installing ArcSDE.

Thanks in advance!
