Magento redirects to page not found for products for some times only

Question

I am facing a strange issue. I donot know that any one faced it or not. When I click on the products in the listing page, sometimes it redirects to page not found page(404page) and some times it goes to the product view page. I have reindexing all the items and cleared cache several times. But no luck. This is happening when I move from old server to new server.

Can anyone suggest me any ideas on this.. I am using magento 1.7.0.2.

If you are working in Linux always check the ownership of your files. Maybe many of the files in your cache are under some user and others from other user. This could be the root cause of the issue.
