Our application is a windows service that uses QuickOPC UA for COM to collect data from devices on the network. We've been conducting a stress test lately and have been observing the following issue :

The Windows service fails and shut down on it's own. A windows system log has been found indicating the following :

I'm sorry it's in french but it's quite understandable.
Apparently it's a .Net Runtime related error.

We're not using any other .Net related components in our application.

Our stress test protocol is the following :

- 14 boolean OPCDA tags changing value every 5 seconds. All together.
- Our app gets the events and act accordingly with our internal algorithm

It worked perfectly fine the time it lasted (around 6 to 7 hours) with CPU usage at decent levels.
It then crashed around 1:06 AM without any error that we were able to catch.

An idea?
