ConnectionRead (WrapperRead())Timeout expired

■环境说明：

数据库系统：Microsoft Server 2000 (Sp4)

操作系统：Microsoft Server 2003 （SP1）

开发环境：Microsoft Visual Studio .net 2003

■代码

SqlCommand SqlComm = new SqlCommand();
2

try
3

{
4

SqlComm.Connection = sqlConn;
5

SqlComm.CommandText = p_ProcedureName;
6

SqlComm.CommandType=CommandType.StoredProcedure ;
7

SqlComm.ExecuteNonQuery();
8

}
9

catch (SqlException myException)
10

{
11

for (int i=0; i < myException.Errors.Count; i++)
12

{
13

errorMessages = "Index #" + i + "\n" +
14

"Source: " + myException.Errors[i].Source + "\n" +
15

"Number: " + myException.Errors[i].Number.ToString() + "\n" +
16

"State: " + myException.Errors[i].State.ToString() + "\n" +
17

"Class: " + myException.Errors[i].Class.ToString() + "\n" +
18

"Server: " + myException.Errors[i].Server + "\n" +
19

"Message: " + myException.Errors[i].Message + "\n" +
20

"Procedure: " + myException.Errors[i].Procedure + "\n" +
21

"LineNumber: " + myException.Errors[i].LineNumber.ToString();
22

}
23

}
24

■说明
执行存储过程p_ProcedureName的过程中,截取到SqlException异常,以上内容如下:

ERROR: Index #0
Source: .Net SqlClient Data Provider
Number: -2
State: 0
Class: 10
Server: DatabaseServer
Message: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.
Procedure: ConnectionRead (WrapperRead()).
LineNumber: 0

究竟原因为何,最终未能调查出来。
最后换了另一种处理方式，将存储过程放到job中执行。然后代码中通过执行存储过程sp_start_job来启动作业，间接执行自定义的存储过程。避免发生该异常。
如果有更好的方法解决该问题，还请赐教！先行谢过！

//执行启动作业的存储过程
2

SqlParameter[] spParams =

{
3

new SqlParameter("@job_name",SqlDbType.NVarChar,128)
4

};
5

//作业名称
7

spParams[0].Value = p_ProcedureName;
8

SqlCommand objSqlCommand = new SqlCommand();
10

objSqlCommand.Connection=objSqlConnection;
11

objSqlCommand.CommandType=CommandType.StoredProcedure;
12

objSqlCommand.CommandText="sp_start_job";
13

for(int i=0 ;i<spParams.Length;i++)
14

{
15

objSqlCommand.Parameters.Add(spParams[i]);
16

}
17

objSqlCommand.ExecuteNonQuery();
