JGroups cluster uses incorrect IP address in RHBK 26.2
Issue
- When configuring a JGroups cluster for RHBK, a different IP address is used for communication than the one specified.
- The server log shows a warning message like
WARN [org.jgroups.protocols.pbcast.GMS] (main) <Node 2>: JOIN(<Node 2>) sent to <Node 1> timed out (after 2000 ms). - Checking network connections with the
sscommand reveals that the Keycloak process is bound to an unexpected IP address, not the one intended for the cluster.
Environment
- Red Hat build of Keycloak (RHBK) 26.2
