Strange: sql.log file

Hi!

This is 8.1.6 on Win2k Advanced Server.

We have a strange thing occuring here: a file named sql.log shows up on c:\ and I can't delete it because it is locked by some process. I looked in the Oracle configuration and all Net8 tracing is done to c:\oracle\ora81\network\log. So this can't be an Oracle log file.

We have no idea where it comes from. Size: 350 MB and growing.

Is there a way to find out what process is generating and locking the file? Here is a sample from the file:

Processid:{3D14 318-6dc	ENTER SQLAllocEnv
		HENV *              7318F510

Processid:{3D14 318-6dc	EXIT  SQLAllocEnv  with return code 0 (SQL_SUCCESS)
		HENV *              0x7318F510 ( 0x009d14f0)

Processid:{9BE6 2d0-708	ENTER SQLSetConnectAttrW
		SQLHDBC             00991C60
		SQLINTEGER                   1 <SQL_ATTR_MAX_ROWS>
		SQLPOINTER          0x00000000
		SQLINTEGER                  -6

Processid:{9BE6 2d0-708	EXIT  SQLSetConnectAttrW  with return code 0
(SQL_SUCCESS)
		SQLHDBC             00991C60
		SQLINTEGER                   1 <SQL_ATTR_MAX_ROWS>
		SQLPOINTER          0x00000000
		SQLINTEGER                  -6
