Sporadic 'Connection refused', locked proxy?

843793Nov 9 2007 — edited Nov 13 2007
I am getting a sporatic 'java.net.ConnectException: Connection refused' exception in an rmi method call. (FYI my use of rmi is vanilla and very simple.) The only clue I've found in the exception (see below) is a 'at $Proxy2.isLocked(Unknown Source)' line. I wonder if the problem has something to do with an rmi property. I am explicitly setting the following properties.
System.setProperty("sun.rmi.transport.connectionTimeout","60000");
System.setProperty("sun.rmi.transport.tcp.handshakeTimeout","120000");
I'd appreciate any thoughts on this. It's difficult to debug, since it appears to be something in the rmi itself.

thanks
