Unhandled exception in System.Transactions stops Windows service during network instability

Question

We start the service based on NServiceBus using the host process NServiceBus.Host.exe.

Twice in production over the past few months, the Windows service unexpectedly stopped working, leaving the following event in the application event log:

Application: NServiceBus.Host.exe Framework version: v4.0.30319 Description: The process was interrupted due to an unhandled exception.
