进程逐步挂起问题
公司现在用的是一款服装类ERP软件,目前有二百多个点。
最近系统常出一个现象,一个进程挂起后,其它进程会陆续挂起,然后下面代理商就会朝我大叫,怎么不好使了呢?

大家有谁知道这是什么现象吗
是某种操作造成的死锁吗?如何按步查找问题原因呢。

我现在只能重启sql服务解决,但是这样可能会丢数据,请助各位了。

------解决方案--------------------
SQL code
--查看谁造成的死锁create procedure [dbo].[sp_who_lock]asbegindeclare @spid int,@bl int,@intTransactionCountOnEntry int,        @intRowcount    int,        @intCountProperties   int,        @intCounter    intcreate table #tmp_lock_who (id int identity(1,1),spid smallint,bl smallint)IF @@ERROR<>0 RETURN @@ERRORinsert into #tmp_lock_who(spid,bl) select 0 ,blocked   from (select * from sysprocesses where blocked>0 ) a    where not exists(select * from (select * from sysprocesses where blocked>0 ) b    where a.blocked=spid)   union select spid,blocked from sysprocesses where blocked>0IF @@ERROR<>0 RETURN @@ERROR -- 找到临时表的记录数select @intCountProperties = Count(*),@intCounter = 1from #tmp_lock_whoIF @@ERROR<>0 RETURN @@ERROR if @intCountProperties=0select '现在没有阻塞和死锁信息' as message-- 循环开始while @intCounter <= @intCountPropertiesbegin-- 取第一条记录select @spid = spid,@bl = blfrom #tmp_lock_who where Id = @intCounter beginif @spid =0             select '引起数据库死锁的是: '+ CAST(@bl AS VARCHAR(10)) + '进程号,其执行的SQL语法如下'else            select '进程号SPID:'+ CAST(@spid AS VARCHAR(10))+ '被' + '进程号SPID:'+ CAST(@bl AS VARCHAR(10)) +'阻塞,其当前进程执行的SQL语法如下'DBCC INPUTBUFFER (@bl )end -- 循环指针下移set @intCounter = @intCounter + 1enddrop table #tmp_lock_whoreturn 0end

SQL code
--杀死 死锁    CREATE Proc [Sp_KillAllProcessInDB]           @DbName VarChar(100)      as      if db_id(@DbName) = Null       begin          Print 'DataBase dose not Exist'      end      else      Begin                Declare @spId Varchar(30)          DECLARE TmpCursor CURSOR FOR          Select 'Kill ' + convert(Varchar, spid) as spId              from master..SysProcesses                  where db_Name(dbID) = @DbName                      and spId <> @@SpId                      and dbID <> 0      OPEN TmpCursor      FETCH NEXT FROM TmpCursor  INTO @spId       WHILE @@FETCH_STATUS = 0          BEGIN              Exec (@spId)          FETCH NEXT FROM TmpCursor  INTO @spId            END      CLOSE TmpCursor      DEALLOCATE TmpCursor            end
