PSOD ESXi 5.1.0.799733

Hi,

There is an install ESXi server has been running for more than three months, suddenly appeared last week following error screen, what is caused by a hardware or software problem?

Looks like a hardware error, but hard to tell. Mind telling us what kind of hardware you're using and if it's on the HCL?

Also make sure the firmware/BIOS is up to date and you might want to run memtest overnight to rule out memory faults.

Hi Ah162,

It most probably a hardware error becuase if you see the lines below in your PSOD, they are pointing to some Memory error. MC here stands for Machine Check.

MC: PCPU1: 4 hardware errors seen since boot (4 corrected by hardware)

MC: PCPU6: 1 hardware errors seen since boot (0 corrected by hardware)

Here you may want to:

1. Check the vmkernel logs for the error. I am sure there is something recorded there.

2. Check the iLO logs and see for any hardware errors.

3. Run the diagnostics report.

4. Upgrade the firmware/BIOS on the server.

5. Patch the host to the most latest one.

Thanks,
