Notes Client 7.0; 6.5.5; 6.5.4; 6.5.3 FP1; 6.5.3; 6.5.2 FP1; 6.5.2 All Platforms


This example shows memory leaks in Java Lotus Notes Agents (tested LN 7.0.1 and 6.5.2).

Run this exapmle for several times!, and look at Java Debug Console! Does anybody know solution to the error ???

Register Oracle JDBC driver means that you get at least 5MB permanent memory leak.

"Garbage collector System.gc()", "Oracle DataSource" or "deregisterDriver()" aren't solutions to the problem. This exaple uses Oracle JDBC drivers 10.2. http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/htdocs/jdbc_10201.html (ojdbc14.jar)




import lotus.domino.*;
import java.sql.*;

public class JavaAgent extends AgentBase {

public void NotesMain() {
System.out.println("... MEMORY USED (TOTAL - FREE): "+ new Float((Runtime.getRuntime().totalMemory()-Runtime.getRuntime().freeMemory())/(1024*1024)) + " MB");
try {
// Register Oracle driver means that you get 5MB permanent memory leak.
DriverManager.registerDriver(new oracle.jdbc.OracleDriver());
} catch (SQLException e) {
e.printStackTrace();
}
}
}


Output from Java console:
... MEMORY USED (TOTAL - FREE): 9.0 MB
... MEMORY USED (TOTAL - FREE): 11.0 MB
... MEMORY USED (TOTAL - FREE): 18.0 MB
... MEMORY USED (TOTAL - FREE): 23.0 MB
... MEMORY USED (TOTAL - FREE): 30.0 MB
......
... MEMORY USED (TOTAL - FREE): 64.0 MB
and then Notes 7.0.1 Crash.... Notes 6.5.2 show java.lang.OutOfMemoryException
