Non Root Install for Spectrum 24.3.x in Linux is causing processd to fail as it is being started twice at the same time.

Issue/Introduction

We noticed that after a non root install using RHL 8.10 and after a reboot, the Spectrum processd process is being started twice at the same time which causes the processd not to be started.

Environment

Spectrum 24.3.x

RHL 8.10

Cause

The `[email protected]` unit file, which was added for Spectrum non-root user support, seems to be causing `processd` to start twice after a system reboot on their latest RHEL 8.10 version. This seems to occur when lingering is also enabled at the OS (systemd) level for the same non-root user. 

Resolution

The manual workaround until this gets fixed in a future Spectrum release

 

1. Confirm the duplicate services:

       `systemctl list-unit-files --type=service | grep processd`

2. Disable the system services:

      `systemctl disable processd.service`

      `systemctl disable [email protected]`

3. Remove the system service files:

      `rm -rf /etc/systemd/system/processd.service`

      `rm -rf /etc/systemd/system/[email protected]`

4. Reload the systemd manager configuration:

      `systemctl daemon-reload`

5. Verify that the entries have been removed:

      `systemctl list-unit-files --type=service | grep processd` (This command should not return anything)

     `systemctl list-unit-files --type=service | grep [email protected]` (This command should not return anything)

 

Additional Information

This is scheduled to be resolved in Spectrum 24.3.13
