Now restored. Restarting the h1hwsmsr computer did the trick.
Here's more detail on what happened:
I came in this morning noticed a connection error on DIAG_MAIN. Opened up the HWS ITMs code and saw that every channel went white. There was no restart in the morning that could have affected TCS. I powercycled the msr computer and was able to rerun the code.
Dave also mentioned that various computer crashes between 2-4 AM local was normal during ER6. He didn't see this problem during O1. We also looked at the memory and CPU usage. Nothing is overloaded
