有很多关于正面SPIDs和均匀的信息-1，-2但我没有找到任何关于Blocked By -3. 有人能帮忙吗？
GUID都是 0，当我sp_who2在MASTERdb 上运行时，它会在 the 上显示 a SPIDof但是56当我尝试它或在它上面运行时它不会出现，而and实例都是.RUNNABLEtempdbkillsp_who2tempdbMASTERtempdb sp_who2SPID 54
编辑：运行时，SELECT * FROM sys.sysprocesses WHERE spid = 56这是被阻塞的 SPID 的输出：
spid 56

Edit2：运行select req_transactionUOW from master..syslockinfo where req_spid = [SPID Number]andKILL '[UOW Number]'时，输出 req_transationUOW 全部为 0，杀死它时出现以下错误：
The distributed transaction with UOW {00000000-0000-0000-0000-000000000000} does not exist.
编辑3：当我运行select * from sys.dm_exec_requests下面的行是输出。这里有什么我可以的kill吗？SPID 不会解除对表的阻塞，我也不想随意杀死所有东西，以防服务器崩溃。
