We have a Windows Service that makes a WCF service call. Normally, it works fine. However, occasionally when we restart the Windows Service, a MessageSecurityException is thrown and everything goes to toss and it is thrown again repeatedly thereafter.
One solution we found is setting AllowedImpersonationLevel to "Impersonation". However, we don't use any impersonation. Also, it is a random issue and not always reproducible. Hence, this solution would be irrelevant.
Any light that someone can shed on this would be highly appreciated.
