Intel X710 vs VMWare ESX: crash and reboot-ESCI lgos suddenly stop

[as20]

Hello, when you were running into this issue, where the ESXI logs suddenly stopped or did they provide any information? I may have a similar set up, but my ESXI logs go dark immediately with no helpful information.

Hi Browniecake,

Thank you for posting in Wired Communities. Can you share more information about your setup? OS version, NIC model, driver version and other relevant information.Thanks,Sharon

I've got nothing in the logs that show anything indicative of why my host keeps rebooting.

1x Dell R640 running ESXI 6.5 CPU is 2x 6138 GOLD. 768GB RAM. Host Seems to reboot during any View Horizon Suite linked clone activity, (vMotion, Provisioning, Cloning, rebooting.)

This is all the ESXI logs show, everything appears to be different for every reboot. It looks like the first thing the kernel logs during a boot is "VMB: 112: mbMagic: 2badb002, mbInfo 0x101688" so I am copying and pasting the last log entry of the vmkernel before the reboot.

1st reboot:

2nd reboot:

4th reboot:

Happy to provide any additional info. Checked iDRAC but the only entry about the reboot says "System CPU Resetting." There are no cooling, thermal, or health warnings.

Hi Browniecake,

Thank you for the information, just to clarify so you mean with the presence of X710 , the host will reboot? Is there any chance to remove the NIC to isolate the issue? Thanks,Sharon

[as20]

this has confirmed to be a power issue. The UPS was overloaded and causing this host to reboot unexpectedly.
