So, I have a dell R210 II running Dell version of ESXi 6.7u3 with 3 VMs: a vSan Witness, vSphere Appliance, and pfsense. I thought about posting this question on r/pfsense, but I guess I’ll start here and check if anyone has seen this before. I’m completely aware this version of esxi isn’t supported on this machine. If you want to post that that’s my problem, fine, but it doesn’t really help. It’s been running fine for a while now.
Basically it is my virtualized router and vsan utility box. It works great and I absolutely love it. But occasionally, and becoming more frequently, the box just freezes. So I’ll explain the circumstances.
It’s kind of hard to tell what is failing, but I believe it to be esxi itself. I’d also appreciate any help in debugging this if Im missing something obvious. When it happens, I notice because internet is down. So since I can’t log into esxi or Dirac, I plugged in KVM and see the greyed out ESXi screen in it’s normal mode. Not coredump mode. But it is completely unresponsive. Can’t f2, can’t f12, etc. A reboot does bring it all back up fine.
Logs show nothing, not in esxi, pfsense, or the appliances.. Like a blank slate, no error before and then the normal boot up logs. No CPU spike, memory seems fine. All I can think is that it’s some kind of vmkernel problem.
I have watchdog running on pfsense to automatically restart failed services, such as my vpn, dhcp server, etc. One time this happened I got an email saying DHCP server had crashed and was being restarted. But the other times no such email.
I have tried that pfsense “offload checksum” fix that people use for unsupported hardware but that didn’t work. I guess I’m having trouble figuring out next steps.
