Thank you gentlemen for replying. I tried the suggestions provided but they did not work. So I checked and saw that the script was working on the machine that had AnyEvent version 5.34 installed. I checked the version of AnyEvent on the machine that has the issue and saw that it was running version 7.02 of AnyEvent. So I downloaded the version 5.34 of AnyEvent and after installion, my application is running fine on the new machine. So I guess the version 7.02 introduced a bug. Thanks again for your replies.
