环境 :IBM X3650+DS3400系统WIN2003+MSCS+SQL2005

故障:

[    [sqsrvres] CheckQueryProcessorAlive: sqlexecdirect failed    [sqsrvres] printODBCError: sqlstate = 08S01; native error = 2746; message = [Microsoft][SQL Native Client]TCP 提供程序: 远程主机强迫关闭了一个现有的连接。    [sqsrvres] printODBCError: sqlstate = 08S01; native error = 2746; message = [Microsoft][SQL Native Client]通讯链接失败    [sqsrvres] OnlineThread: QP is not online.    [sqsrvres] CheckQueryProcessorAlive: sqlexecdirect failed    [sqsrvres] printODBCError: sqlstate = 08S01; native error = 0; message = [Microsoft][SQL Native Client]通讯链接失败    [sqsrvres] CheckQueryProcessorAlive: sqlexecdirect failed    [sqsrvres] printODBCError: sqlstate = 08S01; native error = 0; message = [Microsoft][SQL Native Client]通讯链接失败    [sqsrvres] CheckQueryProcessorAlive: sqlexecdirect failed    这个问题是随机出现,不一定,有时几小时,有时几天,但每次出现这个,集群资源就会自已切换.    硬件我都全部更新了.
