I notice there is a lot of "Application shutdown" log? Anyidea what does this mean?

========================

Occationally we will receive following error while consuming CWS web service:

The socket connection was aborted. This could be caused by an error processing your message or a receive timeout being exceeded by the remote host, or an underlying network resource issue. Local socket timeout was '00:10:00'.

There can be multiple reasons as to why this may happen. However, if this has only been recently occuring, then you will need to ask yourself what has changed before you do anything. However, other than looking at what has changed, you can start by debugging the application pool to find out what is happening. Here is an excellent article on how to accomplish just that:

From there you will have enough data to act upon.
