A customer cancelled a purchased order. Foxfire cancelled all the pick tickets related to the order. Only a part of the orders received the cancellation in Everest while the others did not. The EFI system went offline during the event and restarted. The SKU's were not released from the orders. The orders had to be closed manually to release the items.
C:\Program Files (x86)\Icode\Everest\Client\Utilities\Everest-Foxfire Integration Service\logshow that the pick ticket cancellation was done by a PID that stopped soon as the EFI service was restarted.
