JBoss fails to start because of conflict with port 7500
Issue
- JBoss fails to start because of conflict with port 7500
-
We can confirm there is no other instances of JBoss running on box and there is nothing configured to use port 7500 but we are seeing an error message:
WARN [org.jgroups.protocols.UDP] failed to join /224.0.75.75:7500 on eth0: SocketException: Address already in use
-
The following exceptions appear in the server.log file:
