Может правда в этом дело event id 105 - 106

NLB cluster []: Timer starvation has been detected. This might be due to a denial of service attack or a very high server load. During this period, some connections might fail. If this problem recurs frequently, analyze the threat and take appropriate measures and/or add more servers to the cluster. An informational event log entry will be logged when the attack has subsided.
