I run a simulated mutli-user test in a PC. The test frequently updates a SQLServer database. The test works fine for 10 simulated users. However, when I increase the number of users to 30, I go the following error:
[DBNETLIB][ConnectionRead (recv()).]General network error. Check your network documentation.
The error occurs in various place of the program, but always related to SPT command. I am using OLEDB to connect to the SQLServer. Any idea where the problem is?

Thanks in advance
