Products
Identity Manager (IDM)
Environment
IDM 4.8 Identity Applications cluster.
Situation
The following SEVERE error message was appearing intermittently in the tomcat catalina log on all nodes in the Identity Application cluster.
Dec 29, 2022 7:19:22 PM org.apache.catalina.ha.session.DeltaManager messageReceived
SEVERE: Manager [localhost#/IDMProv]: Unable to receive message through TCP channel
com.sssw.fw.exception.EboRuntimeException: An unexpected exception occurred while performing encryption/decryption.

There were no obvious issues authenticating to the Identity Applications and resource requests and approvals seemed to function normally.
Cause
A second development Identity Applications cluster had been added on the same local network with the default cluster configuration parameters. The multicast and ports used by the new cluster were the same as the existing cluster. These parameters need to be unique for each cluster.
This is caused by a misunderstanding of how Identity Applications clustering is configured.
