IE11 sent RST flag

We noticed that IE11 will send a RST flag to server once in a which causes the connection to the server disconnected. We can't figure out what is it in IE11 that will send RST flag and it happens intermittently. We tested with Chrome and this issue never happens at all.

Anyone can give some advise what can be the cause of the problem? Is it some setting in IE11 that causes this? Seek advise from the experts here.
