Greg,This actually should not have happened. Did you get an exception email that the ES will send you if an exception is thrown? If so, I would really like to see it. We are going to see if we can reproduce this because as of right now, you are the only one that is reporting this...and there are a number of other ES users out there.
You are right in that we had the servers down last night for 3 hours....long story....but in any case, this should definitely not happen. Any additional details and how you discovered this would be great to have so that we can trouble shoot!
