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.
