ExitLong with same fromsignalName entered twice sells twice

[MarketAlly]

I have found that when my strategy is running, if it calls ExitShort() with the same fromsignalName twice it will place two orders which in effect reverses my position. Am I wrong in understanding - I thought if I call ExitShort with the same fromsignalName - it should only allow me to exit what is currently in sequence; meaning I am not calling it quantities rather only the signalName and fromsignalName parameters.

Normally I wouldn't care but because my strategy depends on state from actual closing of the order not requesting - I rely on NT to prevent duplicate submissions to the broker.

Initial Call:
execution='c500f1e1c866459d866e974b0eaee912' instrument='ES 12-15' account='Sim101' exchange=Default price=1905 quantity=1 marketPosition=Short orderId='551d007bc9c741e28c47a78a48cf111d' time='9/24/2015 1:00:01 PM' sod=False

Subsequent Duplicate calls (from a race condition):
execution='2c361d01426f43028bdc03071a888bcd' instrument='ES 12-15' account='Sim101' exchange=Default price=1910 quantity=1 marketPosition=Long orderId='5642ed1045e34145a6c9d323736827ee' time='9/24/2015 1:50:03 PM' sod=False

execution='76df561edf934ea1956537e06966e09e' instrument='ES 12-15' account='Sim101' exchange=Default price=1910 quantity=1 marketPosition=Long orderId='f698be18df4148149f85cb84039c1f41' time='9/24/2015 1:50:03 PM' sod=False

Do I need to manage a working state to resolve this or is this considered a bug in NT? From my perspective, I should be able to call the ExitShort() routine with no quantity and it only closes my order not reverses it regardless how many times I call it if the fromsignalName is the same.

Dave

I am running the same strategy on 3 boxes and it happened only on 1 of them - so I know this must be an issue in NT8 and not my strategy.
