NO_RESULTS message after executing a Transaction

Hi Experts,

I am running a transaction which will load XML file of 2500 records and process it. when I run it, after some time I am getting 'NO_RESULTS' message. and when I try to open the xml file which is under WEB , my workbench is getting hanged.

I wanted to check on forum did anybody faced similar issue before. Do I need to put any timeout setting?

Thanks, Eswar
