Hi, I have developed an application which has retrieved the information from remote location...so i put those in UITableView's Section.In response, i will be getting images also..for this i put the background process(only for images..because the app will take more time to retrieve images than text based information..).It is working fine...But if i scroll the tableview while loading the images..it is going to be crashed....

crash Log:

Tried to obtain the web lock from a thread other than the main thread or the web thread. This may be a result of calling to UIKit from a secondary thread. Crashing now...

could anyone has the solution for this..please let me know..how to resolve this crash...Even i used NSThread class for this.. but i didn't get the solution...

Thanks,

Srinivas G
