Issue

  • During restart of a node in a clustered environment, WARN logs are thrown due to jgroup

  • jgroups receive failures are logged as warnings during cluster node startup
WARN  [jgroups-11,liferay-channel-control,node1-62578][JGroupsReceiver:78] Unable to deserialize message payload
java.lang.ClassNotFoundException: [on all service builder Impl classes]

Environment

  • Liferay DXP 2024.Q1

Resolution

  • Essentially, jgroup is attempting to send messages starting before the system is fully started. These are only deserialization failures that happen until the system is fully started.

  • To resolve this behavior, upgrade to Liferay DXP 2024.Q3+, or request a hotfix built on LPD-33553, if you are still within the Support Coverage window.
