Error on Execution of a SP ASP.NET C# - asp.net

Question

public DataTable RunProc(String sProcName, SqlParameter[] arrParams)
{
string sClassName = "DBAccess.RunProc";
SqlConnection objSqlConnection = null;
try
{
objSqlConnection = (SqlConnection)OpenConnection();
string sLogMessage="Executing Stored Procedure: ["+ sProcName +"] with Parameters ";
foreach(SqlParameter objParameter in arrParams)
{
sLogMessage+=objParameter.ParameterName+" = ";
sLogMessage+=objParameter.Value+" ";
}
logger.Logns(LogLevel.TraceDetail,sClassName," ",sLogMessage);
SqlCommand objSqlCommand = CreateCommand(sProcName, arrParams,objSqlConnection,null);
objSqlCommand.CommandTimeout=300;
SqlDataAdapter objSQLDataAdapter = new SqlDataAdapter(objSqlCommand);
DataSet objDataSet = new DataSet();
objSQLDataAdapter.Fill(objDataSet);
this.CloseConnection(objSqlConnection);
logger.Logns(LogLevel.TraceDetail,sClassName," ","Success Executing Stored Procedure: ["+ sProcName +"]");
this.CloseConnection(objSqlConnection);
if( objDataSet.Tables.Count>0)
{
return objDataSet.Tables[0];
}
else
{
return null;
}
//SqlParameter p= new SqlParameter("PACCOUNTNUM", IBM.Data.DB2.DB2Type.VarChar, 17, System.Data.ParameterDirection.Input, true, ((System.Byte)(0)), ((System.Byte)(0)), "", System.Data.DataRowVersion.Current, null);
}
catch(Exception Ex)
{
logger.Logns(LogLevel.TraceDetail,sClassName," ","Error Executing Stored Procedure: ["+ Ex.ToString() +"]");
this.CloseConnection(objSqlConnection);
throw(new Exception(Ex.ToString()));
}
}
The above mentioned code executes successfully in our production enviroment however all of the sudden we start getting Error in our logs

Answer 1

You're getting the System.Threading.ThreadAbortException exception. It's a classic exception caused by Response.End, Response.Redirect, or Server.Transfer.
Something in your code is code is causing you to attempt to redirect. Possibly a lost database connection?
Unfortunately, the only way to fix this is to debug it or to try to fix it yourself.
Short of debugging (since it's production), you could try throwing log statements in at specific intervals throughout the function to try to narrow down where the problem is. e.g.
logger.Logns(LogLevel.TraceDetail,sClassName," ","Trace point 1")
... do some stuff ...
logger.Logns(LogLevel.TraceDetail,sClassName," ","Trace point 2")
... do some more stuff ...
logger.Logns(LogLevel.TraceDetail,sClassName," ","Trace point 1")
etc. That might be the only way to track this down.
