2019 mac pro kernel panic - crash issue every 24-48 hours left turned on - machine just shuts off for some reason

Having issues with a 2019 mac pro that crashes after about 24-36 hours being left with the power turned on. Any idea what the garbage below actually means? Looks like a kernel panic.

Hi,

If you are experiencing a "memory leak in zone" on macOS (often manifesting as a "Zone map exhaustion" kernel panic), this means a kernel-level process or driver is consuming memory and failing to release it.


The fastest and most effective ways to resolve this issue include:

  • Restart Your Mac: A system reboot instantly clears all kernel memory zones, unloads background extensions, and provides a clean baseline.
  • Identify the Culprit: Use Apple Support Activity Monitor to check if a specific third-party app, background service, or driver's memory footprint is steadily climbing.
  • Uninstall Third-Party Antivirus/VPNs: Background kexts (kernel extensions) from older antivirus suites, firewalls, or VPN clients are the most common culprits for zone memory leaks.
  • Update macOS: Ensure your system is up to date, as Apple frequently patches kernel-related memory leaks in subsequent software updates.
  • Run Diagnostic Tools: For deeper analysis, you can use the free and trusted EtreCheck app to scan for malfunctioning kernel extensions
