I have a glassfish application server Version = Sun GlassFish? Enterprise Server v2.1 (9.1.1) (build b60e-fcs) running in production and every day or so stops responding on the https port (8181) and other ports(8080). Once the server stops responding, other application hosted with that port number stops responding. I've hosted two application in the server.
I searched for clue in log files but could not get one.
I've set thread size to 200.
In netstat i can CLOSE_WAIT status for different hosts.
The server needs to be restarted after it stops responding.
