Hi Kent, thanks for reporting.
Although I'm glad to hear that it actually didn't showed up again, there are actually backup activities running twice a week but they should not interfere at all with the normal board functionality. So far I'll take a look at it.
That said, if a similar situation will happen again in the future, please provide us with the precise time in order to help us browse and verify through the logs.
Cheers, Riccardo
