After performing an upgrade to DX NetOps Topology 25.4.8, older version library files (e.g., 25.4.1-RELEASE) may remain in the Hazelcast library directory.
This is often discovered during file audits or while troubleshooting other performance issues like memory leaks.
/opt/NetOps/netops-topology/hazelcast-5.4.0-slim/libSymptoms: A file listing of the Hazelcast library directory shows multiple versions of the same JAR files:
Cause: A flaw in the upgrade playbook fails to overwrite or delete older libraries during the upgrade process.
Resolution: Fixed in release 25.4.10 and higher. See for steps to download this release.
Workaround for versions 25.4.9 and lower:
/opt/NetOps/netops-topology/hazelcast-5.4.0-slim/lib.25.4.1-RELEASE JAR files if newer versions are present.This will only be seen in upgrades, a fresh install of topology will include the correct libraries
This is fixed in 25.4.10+
