WCF Message inspectors concurrency model

I have implemented message layer security using message inspector mechanism in a wcf service.

On the client side, in IClientMessageInspector.BeforeSendRequest I add an authentication header. On the service side, in IDispatchMessageInspector.AfterReceiveRequest I inspect the authentication header in the message. If it is not found or as expected, I throw a SecurityException and try to log it to a database. Here comes the interesting part. When logging to database, I try to read from this webservice again (this is web service which provides configuration info). This is where the service stalls/deadlocks. I can see that the call to read configuration (when logging to db) is made, but I don't receive the call on the service. I keep getting a timedout exception every time.

After a little googling, I came across this post, which mentions that message inspectors are synchronous in nature. If that is so, how can I achieve what I am after?
