Re: new exception

I'm gonna go ahead and put a lock over GetComissionConcerns GetDecommissionConcerns anyway, although more insight into the situation could help with getting better to know why that happens. Do you have some http handlers that get hit in parallel with your application starting (your container getting composed)? 
Does that happen only the very first time you start the application?
I guess it's very unlikely you add/remove lifetime concerns at any later point, right?

it seems to get triggered by the view:

but it is also not the view's fault. Sometimes it renders sometimes it 
doesn't. And this view code worked very stable in the past. I am not 
using threading anywhere near this code, so I am a bit unsure of how 
to proceed.
The logs are full of this exception and the service is unstable, so I 
am under a bit of pressure...


Any help would be greatly appreciated...

    the only thing, from the top of my head, that comes to mind would be
    that it;s a threading issue -one thread returns commission steps,
    while an other one adds some more between the calls to array.Length
    and array.Copy
