This agent release updates the following bundles:

* agent-process-handling-api 1.0.9: Zombie and dead Linux processes are now excluded from monitoring
* agent-process-handling 1.0.52: Zombie and dead Linux processes are now excluded from monitoring
* agent-jvm-handling 1.0.51: JVMs are no longer attached prematurely during startup; IWS JobManager process no longer causes repeated timeouts in agent discovery

Features

This release adds the following features:

* Zombie and dead Linux processes (kernel states Z/X) are now automatically excluded from the agent's active monitoring set, eliminating spurious sensor activations and wasted CPU cycles on terminated processes.

Fixes

This release includes the following fixes:

* Previously, JVMs that were still initialising (hsperfdata file present but not yet accessible) could be incorrectly attached or silently dropped by the agent. Now, the agent defers attachment until the JVM signals readiness, preventing premature or incorrect attach behaviour especially in containerised and systemd-isolated environments.
* Previously, the IWS JobManager process (/opt/TWA/iws/TWS/bin/JobManager) was incorrectly detected as an attachable JVM due to J9 attach files created as a side effect of its embedded JVM library. This caused a 10-second timeout on every agent discovery cycle. Now, the agent correctly identifies and ignores this process.

Internal updates

These changes improve internal stability and prepare future enhancements:

* sensor-api 1.2.184
* agent-json 1.2.184
* agent-cgroup 1.0.13
