Active Show Server Failed - 3.6.1

Had an interesting pop up last night.

We had been on the show all day...just finished the event and were starting strike. A pop-up on the console appeared that said:
"The active show server Server-1-0090a10f1519 has failed. No backup server has been detected. For more information, please consult the network window."
No yellow triangle...
Opened the network window and all processes were running...
Playback was still operating...

Hit "OK" and the box went away. Continued with strike. Came back about 15 minutes later and the pop-up was back. Hit "Ok." Came back...ok...came back. Would not go away. However, playback and operation never stopped.

No log files were created.
