If you host FiveM or RedM servers on modern Windows operating systems such as Windows Server 2025 or recent Windows 11 updates you’ve likely seen your FXServer console getting endlessly spammed with process monitoring execution errors.
It’s one of those classic infrastructure headaches: an upstream dependency quietly deprecates a decades old tool, and suddenly your production logs are flooded with failure messages every few seconds.
Here’s a breakdown of why this is happening and a direct patch you can apply to txAdmin to fix it without sacrificing performance monitoring.
The Root Cause: Legacy Tooling Meets Modern Windows
At the core of the issue is Microsoft’s long announced retirement of wmic.exe (Windows Management Instrumentation Command-line). On newer Windows builds, wmic has been completely stripped from the OS.
txAdmin relies on two internal Node.js utilities to monitor process health and gather performance metrics for your FXServer instances:
pidtree: Tracks active server binaries by mapping process IDs to parent processes.pidusage: Pulls CPU and memory usage statistics.
By default, both of these underlying packages fall back on calling wmic under Windows environments. Because wmic.exe no longer exists on modern builds, every polling cycle fails, dumping continuous execution errors straight into your server terminal.
The Solution: Swapping WMIC for PowerShell CIM
Instead of waiting for upstream packages to push updates, we can patch txAdmin’s bundled monitor entrypoint directly (server\citizen\system_resources\monitor\core\index.js).
We redirect both monitoring utilities away from wmic and onto modern PowerShell CIM instances (Get-CimInstance), parsing the results as JSON.
Step 1: Locate and Back Up the Entrypoint
Navigate to your server artifact directory and locate the target file:
\server\citizen\system_resources\monitor\core\index.js
Always create a backup copy (index.js.bak) before modifying core system resources.
Step 2: Patch pidtree (Process Tree Listing)
Inside index.js, search for the pidtree logic that builds the process query (look for wmic PROCESS get ParentProcessId,ProcessId).
Replace that execution string and its whitespace parser with a PowerShell query returning structured JSON:
powershell.exe -NoProfile -Command "Get-CimInstance Win32_Process | Select-Object ParentProcessId, ProcessId | ConvertTo-Json"
Then, update the handler to parse stdout via JSON.parse() rather than relying on WMIC's legacy text table formatting.
Step 3: Patch pidusage (CPU & Memory Metrics)
Next, find where pidusage queries hardware stats (look for wmic PROCESS where).
Swap out the legacy call for the PowerShell Get-CimInstance equivalent:
powershell.exe -NoProfile -Command "Get-CimInstance Win32_Process -Filter 'ProcessId = %PID%' | Select-Object CreationDate, KernelModeTime, UserModeTime, WorkingSetSize | ConvertTo-Json"
Because the JSON property keys returned by Get-CimInstance match the original WMI field names, you can feed the parsed object directly into pidusage's history module. The CPU and memory delta calculations remain identical.
Verifying the Patch
Before launching your server, open PowerShell in the monitor\core directory and run a quick syntax check:
node --check "index.js"
If Node returns clean, boot up FXServer. You should immediately notice:
- The constant
wmicerror spam in your console is gone. - The txAdmin Web Panel dashboard continues to plot real-time CPU and RAM graphs without interruption.
Since this modification only swaps out the data collection provider without touching calculation formulas, your performance metrics remain accurate while keeping your server logs clean.
