Unhandled NullReference exception at PassThroughProcessor.Process crashes application #928

Description

@rikbosch

Hi,

We've had an application crash, with a stackstrace coming from application insights PassThroughProcessor:

(source: windows event-log)

Application: Ao.TnT.Grains.Host.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.
Exception Info: System.NullReferenceException

We have 2 applications reporting with the same insights key.

We're running several instances of these applications in a Service Fabric cluster. The weird thing is that all of the instances crashed, reporting the same stacktrace at the same time in our cluster.

Any idea's what could be causing this?
