Operation time out

Question

I am calling a thread in code behind as follows

 

System.Threading.Thread th = null;

th =  (new System.Threading.ThreadStart(AsynchronusWeb));

th.Start();

 

In  AsynchronusWeb methode  i am processing large files. At certian time it show an error in event viewer like operation time out. How can i handle that. It will not show any error in browser.
