C# call GlobalDictInterface.Update works fine and then it doesn't

[lgeissbauer-btig]

the following works just fine:

julia> for i in 1:10000 GlobalDictInterface.Update("c1", "k$i", "v$i"^1000) end

But stress testing it it doesn't:

julia> while true; for i in 1:1000 GlobalDictInterface.Update("c1", "k$i", "v$i"^1000) end; sleep(1); end
ERROR: CLRException: System.MissingMethodException: Method 'GlobalDictInterfaceForJulia.GlobalDictInterface.Update' not found.

But trying after the error happend it works again:
