Here's the process listening on 8080 on server #1 [r...@esbuat1a ~]# lsof -i :8080 COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME java 15511 jboss 184u IPv4 81259 TCP ESBUAT1A.intranet.mydomain.com:webcache (LISTEN) and on server #2 [r...@esbuat1b ~]# lsof -i :8080 COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME java 23474 jboss 194u IPv4 431570 TCP ESBUAT1B.intranet.mydomain.com:webcache (LISTEN) I should also note that I can telnet directly to the backend servers on port 8080. Any ideas?
