Hi Shrinivasan,
There is a visual indication of whether there is any content on talk page. When you are on the article page, if you see talk page link in blue, it means there is content on the page and if the talk page link is red, it indicates that the page doesn't exist. Unless you want to start a discussion and/or create a talk page you shouldn't be clicking on that.
Hope this helps. Questions like this, in future, could be asked on village pump page of related wiki where local users could assist better.
Regards,
Dhaval Vyas
