Tableau Prep Conductor Process in STATUS_UNAVAILABLE State After Upgrading to Tableau Server 2025.1

After upgrading Tableau Server to version 2025.1, the Tableau Prep Conductor process is in an STATUS_UNAVAILABLE state.

The following error is recorded in stdout_flowprocessor_*.log:

Unrecognized VM option 'UseConcMarkSweepGC'
[ERROR] Error -6: Failed to initialize Java VM.
This option may be removed in a future release.

Cause:

Starting from 2025.1, Tableau Server uses Java 17, which does not support the UseConcMarkSweepGC JVM option.

This issue will occur after changing the flowprocessor.vmopts setting to include the UseConcMarkSweepGC JVM option. For example:

tsm configuration set -k flowprocessor.vmopts -v "-XX:+UseConcMarkSweepGC -Xmx2048m -Xms2048m -XX:+CrashOnOutOfMemoryError -XX:-CreateMinidumpOnCrash -Dspring.cloud.bootstrap.enabled=true"

The Java VM fails to initialize if the UseConcMarkSweepGC JVM option persists, preventing the process from starting. 

Ratkaisu
Run the following TSM command to update flowprocessor.vmopts with options compatible with Java 17.
Note: This command removes the unsupported UseConcMarkSweepGC option and also replaces CreateMinidumpOnCrash with CreateCoredumpOnCrash as the former is also deprecated.
Steps:
  1. Open a command prompt as an administrator on the computer running Tableau Server.
  2. Run the following command:
    tsm configuration set -k flowprocessor.vmopts -v "-Xmx2048m -Xms2048m -XX:+CrashOnOutOfMemoryError -XX:-CreateCoredumpOnCrash -Dspring.cloud.bootstrap.enabled=true"
  3. Apply the pending changes by running the command below:
    tsm pending-changes apply
