I recently migrated my data drives and USB boot drives to new hardware, and I had to reset FreeNAS to defaults to get networking to start properly. I've finished setting all my configurations back to their previous values manually, and my system seems to be performing well.

After about 24 hours of running properly, the smartd service starts alerting with repeated messages "smartd is not running" with a clear message for the alert following shortly after.

While this is happening, the system seems to be performing very slowly both through the UI and command line access. Simple commands like top take many seconds to actually launch.

I've been monitoring /var/log/messages and htop, and I'm not seeing any obvious errors or resource contention.

Please find the attached debug report.
