The problem described in this article and the proposed solution refer exclusively to Proxmox.

Problem

If you have installed the RCCMD Linux Agent on Proxmox and the agent generally works correctly, it can still happen that regular warning messages in the Linux log are generated.

Typical characteristics:

• Multiple identical warning messages per minute

• The messages refer to RCCMD files that are recognized by the system as executable

• Shutdown tests still work flawlessly

• Monitoring triggers continuously even though no functional problem exists

This behavior is particularly disruptive when a central monitoring system automatically evaluates or escalates log warnings.

Cause

The warning messages occur because two files of the RCCMD Linux Agent are assigned execution permissions (execute bit), even though they do not need to be actively executed by the system in this context.

Solution

If you experience this issue, you can permanently suppress the warning messages as follows without affecting the functionality of the RCCMD Agent:

Procedure

1. Remove the execution permission
   Remove the execute permission from the affected RCCMD files

   /etc/systemd/system/RccmdConfig.service

   /etc/systemd/system/RccmdCtl.service

   the execute permission (x).

    

2. Restart the RCCMD service
   The restart can be done either:

   • via the RCCMD Web UI

   • or directly on the Linux system
     itself.

3. Perform a functional test
   Afterwards, perform an RCCMD shutdown test or RCCMD message test to verify correct operation.

Result

• The recurring warning messages in the Linux log no longer occur

• Monitoring remains free of unnecessary alarms

• The RCCMD Linux Agent continues to operate fully and stably

Note

This behavior is related to the permission assignment of individual files on Proxmox.
It has no impact on the shutdown functionality, but can lead to unnecessary log noise if not adjusted.
