The error occurred while processing a service transaction updating  cash limits. To resume trading, exchange staff rebooted and conducted pre-launch testing of the trading system’s core. The system was open for order cancellation from 10:30 pm MSK, trading was resumed at 11:00 pm MSK, and proceeded to the close normally. As a precaution measure, Exchange operators enabled additional logging of certain operations in the system.”
