Hello,

We see the following exception every other day on our front end servers:

System.ArgumentException: Key duplication when adding: sessionState
  at System.Collections.Hashtable.PutImpl (System.Object key, System.Object 
value, Boolean overwrite) [0x00000] in <filename unknown>:0

Seems like there is a race with ASP.NET startup on multi-core machines. We are 
running 2-10 bits.

Anyone seen this before?

Thanks!
