In 1st Thread:-> For fetching 



string queryFileString = queryFile;

		else

In 2nd Thread:-> For writing values

Debug Values:->

----------

value of queryFile -> "C:\windows\Logs\Tsql\Jul2009.sql"



value of queryFileString ->"C:\windows\Logs\Tsql\Jul2009.sql"



value of currentMap = 1





ThreadMutexMapPrimary -> [1](("C"\Windows\Logs\Tsql\Jul2009.sql",0x0201bae)) --> value in 1st thread



ThreadMutexMapPrimary -> [1]((0x0201ff74 {_Bx={...} _Mysize=??? _Myres=??? },0x0201bae)) -> value in second thread,changes and is crashed.



newFileName.c_str() -> "C:\windows\Logs\Tsql\Jul2009.sql";-----> to be deleted and new the value of thread mutex map to be inserted.
