Ravi, We had previously used 10.2.0.3 on a server. For a new server install, I suggested installing 10.2.0.4, so asked the vendor if they objected. The response was "there are rumors 10.2.0.4 has a memory leak for JDBC driver again". Unfortunately no bug number. I didn't find anything on Metalink, but searching isn't very reliable. Is the JDBC driver on the server or client? Dennis Williams
