Hi, Apology for cross-posting. Posted this on the wrong forum. I have several ESTABLISHED sockets from my Weblogic(Solaris box 1) server to another Weblogic on box2. tcpListenDrop has a high value on box 1. I am not an expert but I don''t think there is any easy way to figure out what request these sockets are blocking for and what threads hold those sockets. So I have turned to DTrace. The information that we need 1. What request( JSP / CSS etc. ) is the socket waiting for ? 2. What thread is holding what socket ? What is the status ? 3. What is not responding in time on box 2 ? This melt-down of the servers is a recurring occurence. How can DTrace help in this case ? I am also reading up on the various DTrace options. I have also read that DTrace can trace even JavaScript calls from the browser all the way upto the database. Really appreciate any ideas. Thanks, Mohan -- This message posted from opensolaris.org
