ROES Server Repeating Heartbeat Communication Error

Use this article when a newly installed ROES Server  repeatedly logs an EnsembleCommunicator(doHeartbeat) communication error in a single-server environment.

Product: ROES Server v3 Category: Launch / Settings Audience: Lab / Support Article ID: 7
Common symptom
A newly installed ROES Server v3 repeatedly shows this message in the Messages pane or log:
EnsembleCommunicator(doHeartbeat) – Communication Error: For input string: ""

When This Applies

This fix applies to a single-server environment. In that setup, ROES Server should be configured to run isolated.

Fix Steps

1

Stop ROES Server activity

Stop everything, including printers and the ROES Server.

2

Open Settings

Click the cog icon at the upper right to open Settings.

3

Enable Run isolated

In the upper-left quadrant, check the box for Run isolated.

4

Apply the setting

Click the nearby Apply button in the same area.

5

Return to the main panes

Click the Back button at the upper left to return to the main ROES Server panes.

Expected Result

After Run isolated is enabled and applied in a single-server environment, the repeating heartbeat communication error should stop appearing in the Messages pane and log.

Important Note

Use this procedure only after confirming the lab is running a single-server environment. Multi-server environments may require different coordination settings.

Escalation Notes

  • Confirm the install is ROES Server v3.
  • Confirm the error is repeating in the Messages pane or log.
  • Confirm the environment is single-server before enabling Run isolated.
  • If the message continues after applying the setting, collect the ROES Server log and confirm whether any printers or agents are still running.
