SPARC: EP Service Creates Defunct Processes Every 24 Hours (16311652)

The Electronic Prognostics (EP) software, which analyzes telemetry data from a variety of physical sensors, creates a defunct process every 24 hours. As a result, performance issues can build up over time.

Workaround: Choose one of the following workarounds:

  • Identify the process IDs (pid) of the defunct processes. Then, use the preap command to force the defunct processes to quit. Defunct ("zombie") processes are marked with a "Z".

    # ps -ecl | grep "Z"
    # preap defunct-pid

    If there are multiple zombie processes, use the following command to kill all processes at once:

    # ps -A | grep defunct | awk '{print $1}' | xargs preap
  • Restart the system/electronic-prognostics service.

    # svcadm restart electronic-prognostics
