Don’t worry this is nothing but due to the heavy traffic on your site this is bound to happen because it makes server so much busy than the normal functional processing.

For coping out from this problem the solution is more servers need to be added to distribute the load among the group of servers, which is also known as a server cluster .

The load servers works for because the load distribution among these servers is known as load balancing. Load balancing applies to all types of servers.

Load Balanced technology allow a group of servers to intelligently service requests made to a host name. This high performance architecture allows for significantly greater performance than can be get by a single server.

If a server fails then the request will be routed to another server as a result, downtime related to server failures or administrative maintenance can be significantly reduced.
