c# - an unsecured or incorrectly secured fault was received from the other party -

I have a Windows program that is calling the WCF service. After some time the service is slowed down and eventually this error Faced with an "unsafe or wrong-safe mistake from the other side". Restart once again after starting the service. with honesty.

Sorry, but due to slowing down your service there are thousands of reasons for most of them with WCF Nothing will happen, I strongly suspect that you have a resource leak of some kind, but it is impossible to tell that it is without much information.
