@SeanFeldman something tells me that we are going to need a lot more info to diagnose this then just a stacktrace

Not an issue with ninject.

WilkoSki commented 9 years ago

@SeanFeldman, @johnsimons we've managed to get to the bottom of the issue. Essentially the problem is due to the UnicastBusConfig section containing the ForwardReceivedMessagesTo="audit" setting.

This must have been carried over from earlier versions of NSB in our solutions, however v5.1.3 doesn't manifest the issue where v5.2.0 does.

Looking at the auditing config documentation it would appear that this setting was from v3.x and it's not intended to be used in v.5x. So it's a non-issue.
